A Guide To Electricity

To connect electricity
To connect electricity
When you first move in and connect the electricity supply, turn all the switches on the breaker board to "ON," and confirm whether the electricity is being supplied or not. Once confirmed, contact your local Kansai Electric office to notify your name, address, the date of occupancy, and your customer number which is written on the envelope placed near the breaker or the meter.
Even if the breaker switch is ON, if there is no power, a repair person from Kansai Electric may be called.
If you wish to use an electric water heater, wiring and meters will be connected once your application has been accepted. You can start using the heater from the day after wiring is carried out, in order to heat water at night.
Breakers
Breakers are usually installed on a distribution board located in the entrance of the residence. The breakers consist of an earth leakage breaker (a main breaker) and safety breakers. (Some distribution boards have no main breaker.)

To disconnect electricity
When you move out, you must arrange to have your power supply disconnected. Contact the nearest Kansai Electric office 4 or 5 days before moving and notify your name, the date you plan to leave and your customer number.

POWER GENERATION

Outline of Thermal Power Generation

Electricity demand varies greatly by season and time of day. Because thermal power generation can flexibly adapt to changes in demand, it plays a central role in maintaining the power supply.
By combining various power sources, we can provide the quantity of power required to accommodate demand for the season and time of day.

Type of power supplyOperational patternFeatures
Coal-fired thermal powerBase-load operationMuch like nuclear power, coal-fired thermal power is generated around-the-clock and the output is constant. It cannot be adjusted to respond to power demand fluctuations.
LNG-fired thermal powerBase-to-middle-load operationThese sources of power can be made to respond flexibly to daily fluctuations in electric power demand. They operate during the daytime, stop at night, and repeat this pattern daily.
Oil-fired thermal powerMiddle-to-peak-load operationThese sources of power can be adjusted to accommodate peaks in electricity demand. They are operated mainly in summer and winter during periods of high demand. Otherwise they remain on standby and are ready to run at any time to provide reserve power when the demand spikes unexpectedly.
The burning of fuels such as oil, coal and LNG (liquefied natural gas) fires a boiler to generate high-temperature, high-pressure steam. This steam is used to drive a steam turbine. A generator attached to the steam turbine generates electricity.
Steam power generation
 

Fuels such as heavy oil, LNG (liquefied natural gas) and coal are burned inside a boiler to generate steam at high temperature and high pressure.
This steam is used to rotate the impeller of the steam turbine. This drives the power generators connected to the turbine that generate electricity.
This system has a thermal efficiency of around 42% to 46% and functions as a base-to-middle-load supply.
Power stations utilizing steam power generation
  • Nanko Power Station
  • Maizuru Power Station
  • Ako Power Station
  • Aioi Power Station
  • Himeji No. 2 Power Station (Unit Nos. 5 & 6)
  • Kainan Power Station
  • Gobo Power Station
  • Tanagawa No. 2 Power Station (Under a long-term planned outage)
  • Miyazu Energy Research Center (Under a long-term planned outage)
Combined cycle power generation

This method of generating electric power incorporates a gas turbine whose waste heat is reused to drive a steam turbine. The gas turbine is powered by high-temperature combustion gas that, after being discharged from the gas turbine, is efficiently recovered by means of a heat recovery boiler. This produces steam of sufficient temperature and pressure to drive the steam turbine and generate electricity. This configuration ensures high thermal efficiency, as the cost per unit of power generated is lower than that of oil-fired thermal power. It is used to provide the base-to-middle-load supply.
Power stations employing combined-cycle power generation
  • Himeji No. 1 Power Station (Unit Nos. 5 & 6)
  • Himeji No. 1 Power Station (Unit Nos. 5 & 6)
  • Sakaiminato Power Station
Gas turbine power generation
 

This electricity generating system makes electricity by burning fuels such as LNG (liquefied natural gas) or kerosene to produce high-temperature combustion gases with sufficient energy to rotate a gas turbine.

20 Tips for Engineering Students To Excel




Getting your engineering degree is a ticket to rewarding careers, and sometimes a handsome paycheck. But before you enter the field as a professional engineer, some serious studying, a few late nights, and a few tips to get you through your first year are in order.
Tip #1: Take good notes, and keep them all after your classes are over.
Engineering textbooks can be dense, but endure through the tedium. Do your reading – all of it – and keep a highlighter and page markers handy. After the class is over, keep your most useful and well-written textbooks as reference. Your notes, annotations, and highlighting will be invaluable later on. You may even want to keep a “Rules of Thumb” notebook, allowing you quick access to your most-used formulas.
Tip #2: Get to know your professors.
Develop a relationship with your professors so you feel comfortable approaching them and asking for help. Get to know one or two key professors particularly well, and turn to them for help with your homework, insight into the industry, and even job or program references.
Tip #3: Ask questions, both in class and out.
Your professors want you to learn. But if the only thing you ever ask is, “Will this be on the test?” then you are not taking advantage of their knowledge or willingness to help. Ask for additional examples to clarify difficult equations and concepts. More often than not, your fellow students will thank you for speaking up, and your professor will appreciate your active investment in the material.
Tip #4: Try to solve a problem before asking for help.
No one wants to do your homework for you. You’ll be more likely to get help if you’ve already begun the effort. Even if you’re totally lost, make a legitimate, prolonged effort to solve a problem before asking for help. When you do seek help, be prepared to discuss what you tried already, and bring your scratch paper showing your attempts.
Tip #5: Form a study group.
Working alone can get exasperating if you find yourself stuck on a problem. Working with others will not only introduce other viewpoints to approaching a problem, it will also provide encouragement and camaraderie in the face of frustration.
Tip #6: Teach someone else.
One of the most effective ways of ensuring you understand something is by explaining it to someone else. Before you move past a subject, make sure you not only answered the question but also can replicate and explain the process. Each new subject and concept will build on the last, so don’t move on until you’ve mastered each new idea.
Tip #7: Diversify your engineering classes.
Take classes in all sorts of engineering, even if they are not your concentration. Understanding not only the subject matter, but also how other types of engineers approach and solve problems, will lend insight into your own field, from biomedical to mechanical to chemical to environmental engineering and beyond.
Tip #8: Take classes outside engineering, particularly design classes.
The most successful engineers are insatiable learners, so seek to broaden your skill set generally. A design class can teach you how to represent information visually and how to talk about an idea from a big picture perspective. A writing class can hone your skills for communicating your ideas to others. A business class can prepare you for organizational tasks and leadership roles later in your career.
Tip #9: Hone your communications skills, including conversation, writing, and presentation.
The best and most innovative ideas in the world have no hope of growing past the drawing board if you are unable to communicate them effectively. And today, most technical communication between team members and leadership happens over email, which is a form of writing. Learn to present an argument simply and without agenda, and always read your emails through once or twice before sending.
Tip #10: Learn another language.
Engineering knows no political or cultural borders; engineers are in demand everywhere in the world. Increase your worth by becoming proficient in another language, and don’t be afraid to think of your career on a global level. Want to build bridges in China? You should learn Mandarin.
Tip #11: Build your portfolio.
Participate in as many hands-on projects as possible, especially those outside the classroom. Future employers look for both coursework and relevant experience, and a well-organized and articulate portfolio will be invaluable during your job search. Your practical project experience will also reinforce the “in theory” knowledge you gain in class.
Tip #12: Get a summer internship.
One of the best portfolio buildings blocks is the summer internship. Internships do more than build your resume; they demonstrate to potential employers that you can commit to a long-term role and work as part of a team.
Tip #13: Build your network.
Do not wait until you need a job to start building professional relationships. In addition to getting to know your professors and peers, attend extracurricular lectures, workshops, and networking events, and get to know as many people working or studying in your field as possible. Take a genuine interest in the work of others, ask lots of questions, and don’t be afraid to seek guidance or advice from those of advanced experience. They were once neophyte engineers too!
Tip #14: Scour the resources of professional engineering associations and companies.
Professional engineering associations, such as the National Society of Professional Engineers, are an invaluable resource for jobs, advice, and networking. Identify organizations that share your values and interests, and make as many contacts as possible.
Tip #15: Skip the honors class.
In the engineering field, your GPA matters. If you struggle in calculus, don’t kill yourself in Honors Calc; take the easier class, learn the material thoroughly, and take the higher grade.
Tip #16: Learn when to lead and when to back down.
Engineers often work in teams, and every team has one or more leaders. You should feel comfortable in both leading and following the directions of others. Hone your leadership skills and learn how to effectively influence group decisions, but recognize when your contribution should be to take orders and follow direction.
Tip #17: Work on the problem before the team meets.
The best results occur when a group discusses ideas that have already been fleshed out by individual members. Learn to do your own work and self-motivate. Always arrive at the team meeting with ideas in mind.
Tip #18: Be a perfectionist.
In the words of one engineer, “In the working engineer world, a 99% correct product can cost millions of dollars in damages.” Adopt the mindset of practicing something until it is perfect, as opposed to going as quickly as possible and settling for a B. When your work is 100%, even if it is slower, it is valuable.
Tip #19: Identify your inspiration.
What made you decide to study engineering? Who do you look up to in your chosen field? Learn about how individuals and companies have sought and found success, and replicate their behaviors.
Tip #20: Take heart and persevere.
Engineering is a difficult course of study for everyone, no matter their IQ or test scores. Frustration can lead to feeling like an imposter. Every future engineer has struggled through seemingly impossible problem sets, cranky professors, and gut-wrenching exams. In the face of inevitable small failures, recognize that you are challenging yourself like never before, and push on through the difficult experiences.

PENGASSAN SUSPENDS STRIKE

ABUJA—THE leadership of Petroleum and Natural Gas Senior Staff Association of Nigeria, PENGASSAN, yesterday boycotted the meeting with the Minister of Labour and Employment, Senator Chris Ngige and the Minister of State for Petroleum, Dr. Ibe Kachikwu, complaining that the invitation to the meeting from government was impromptu. PENGASSAN also said the strike it embarked upon was still ongoing and that there was gradual shutdown of depots and refineries, adding that the three day Sallah break was responsible for the slow start of the strike. But the ministry of Labour and Employment has said that the scheduled meeting between government and the leadership of PENGASSAN and NUPENG was re-scheduled till today because of the Sallah break. The Deputy Director, Press, in the ministry, Samuel Olowookere, told Vanguard on phone that “it has been postponed till Monday morning at 11a.m., and the same venue because of the Sallah and public holiday.” Already, Vanguard was told that representatives of the Nigeria Union of Petroleum and Natural Gas Workers, NUPENG, were in Abuja yesterday for the meeting only to be told that it had been rescheduled as the sister union, which declared the strike, PENGASSAN, stayed away. Explaining why the meeting could not hold as scheduled, the National Public Relations Officer, PRO, of PENGASSAN, Comrade Emmanuel Ojugbana, told Vanguard on phone that there was no way the association could have attended the meeting because the invitation was quite impromptu. He also said that PENGASSAN had not met to decide on the new date to meet government, adding that the Monday meeting the government had mentioned was not agreed by the relevant parties. He said: “They just sent invitation to us yesterday, (Wednesday), it is quite impromptu. Most of our people are scattered everywhere, we need to reach them with the information.”

Atiku and Nigeria’s power problem

MOST people would not dispute a high mark for former Vice President Atiku Abubakar as a public speaker. Or the quality of his interventions on national issues, like his speech at the public presentation of We are all Biafrans, a book by the Nigerian journalist and activist Chido Onumah, held at the Yar’Adua Centre, Abuja, on May 31, 2016.
He is “atikulate,” if I may assume the lexical license to use his name to modify a familiar word. He also has a firm grasp of issues that engage his interest.
In fact, unlike him, most Nigerian leaders at his level and above, with the exception of those in the First Republic, have tended to be inarticulate and to have a weak grasp of issues and an even weaker capacity to analyse them knowledgeably and with insight.
The country can be said to suffer from kwashiorkor of the intellect, with the dismal performance of most of its leaders in the cerebral department providing the basis for an accurate diagnosis.
But if Atiku had not always proven to be an exception to this sorry norm, he did so in the said speech widely publicised in the subsequent day’s newspaper lead stories as a call for the restructuring of Nigeria.
Nor did he disappoint when he spoke extempore at the event, fielding questions from the compere on sundry issues related to and beyond those he addressed in his prepared speech. The same clear-sighted view of issues and cogent articulation of his positions were evident as in the formal speech.
Some of the issues he addressed outside his speech were in relation to the Nigerian power sector and its seemingly irremediable under performance. And though this aspect of his remarks did not generate as much interest from the media as his call for the restructuring of Nigeria, I consider it equally important and deserving of such critical attention as I intend to pay it here under.
His remarks on our power sector arose from his story of how he visited the Philippines as Vice President and realized that the Filipinos had problems of low power generation like us. According to him, they solved this problem by resorting to captive power, and in a few years generated enough power that they insisted on their then president continuing in office at the next election.
He then noted that on his return he recommended that we adopt captive power like the Filipinos as the means of solving our power problems. He affirmed that if we did we would have had the issue of inadequate power generation behind us in a few years, like the Filipinos.
He went on to criticise our choice of gas as the means of powering the NIPP stations we built instead of cultivating captive power as he recommended. He justified this criticism with the menace of vandals and the general instability in the Niger Delta, the main source of gas for our power stations. He then expressed strong reservations that we will “get it right” in the power sector until we resolve the problems in the Niger Delta.
And since the prospects of resolving those problems are not in sight, it would seem safe to conclude, from his analysis, that, unless we resort to captive power as he recommended, we may not soon see the proverbial light at the end of the tunnel or shall, thanks to the problems in the Niger Delta, continue to drill a tunnel for ourselves away from the promise of light.
His was, for me, a sombre, though-provoking, almost depressing summation. But I do not entirely agree with him.
First, I must admit that, as he suggested, it would be near impossible to expect to generate steady, let alone sufficient, power in our country from gas so long as the current unrest – the sabotage and other symptoms of socio-political anomie – persists in the Niger Delta.
But it does not follow that our choice of gas was wrong. Gas, being a plentiful resource in our country, was a low-hanging fruit, to paraphrase the former Minister of Power Prof. Bart Nnaji. And since it had worked for us in facilities like Sapele and Ughelli power stations in the pre-Niger Delta crisis era, it was sensible to resort to it as an energy source in the further development of our power sector.
So the choice of gas was not the problem but our inability to manage other factors that have made gas unable to work for us as effectively as it should.
“A captive power plant is a facility that is dedicated to providing a localised source of power to an energy user. These are typically industrial facilities or large offices. The plants may operate in grid parallel mode with the ability to export surplus power to the local electricity distribution network.” (Source: https://www.clarke-energy.com/captive-power-plants/).
So captive power is distinguished by its having a dedicated cluster of consumers; and an energy source would still be required to generate it. The energy source can be gas, as in the case of the Geometric Power plant near Aba. It can be hydro, as in the case of the NESCO facility in Jos. Both are captive power plants. It can be wind, solar or biomass depending on availability.
And if we could allow gas to be sabotaged for on-grid power, and allow those who sabotage it to succeed in holding our country to ransom and profit by doing so, what is the guarantee that the same gas or other energy source or the associated power infrastructure cannot similarly be sabotaged in the case of captive power?
Unlike us, Filipinos did not have a dedicated army of unpatriotic citizens – vandals and saboteurs waging war against their nation to ensure that the power sector remains dysfunctional. They did not have a country in which some citizens would egg on such saboteurs to satisfy their urge to see a serving government portrayed as ineffective and its political fortunes nosedive at the polls.
So we cannot expect what worked for the Filipinos to work for us without considering the differences in our respective local conditions. And it is those local conditions – a slew of abnormalities generally referred to as the Nigerian factor, and not unconnected to bad politics – that have prevented a remarkable captive power initiative like the Geometric Power plant from becoming operational years after its due date.
So captive power is not necessarily the solution to our power problems but can alleviate them if properly managed and freed from such factors that have hamstrung our generating power through gas.
Besides, our country has invested so much in gas-powered plants that it would be a huge waste to abandon it for captive power, which should at best complement options of grid power.
Our best option is to win over the forces preventing us from realising our full potential for generating power through gas, be they in the Niger Delta or elsewhere.

Formal Nigerian Coach “Amodu Shuaibu” Is Dead-another tragedy


Only three days after the passing of former Super Eagles’ Captain and Coach Stephen Keshi, the only man to have coached Nigeria’s senior team on four occasions, Amodu Shuaibu, has died.
Shuaibu-AmoduFamily sources confirmed that the 58 –year old, who was confirmed as National Technical Director by the Nigeria Football Federation in October 2014, complained of chest pains on Friday night, and did not wake up on Saturday. Chairman of the Edo State Football Association, Mr. Frank Ilaboya, said that he had been informed by the Edo State Commissioner for Information, Kassim Afegbua, that the remains of the celebrated trainer had been deposited at the Stella Obasanjo Hospital in Benin City – incidentally the same facility where Keshi’s remains are kept. NFF President Amaju Pinnick was devastated: “This is another tragedy too many. We are still talking about Keshi’s death, and now Amodu is gone. I’m short of words.” One of the best coaches that Nigeria has produced, Amodu Shuaibu first took charge of the Super Eagles at the age of 36, following the departure of Dutchman Clemens Westerhorf as Nigeria left her debut appearance at the FIFA World Cup in the USA in 1994 at the Round of 16. His first match with the Eagles was the famous ‘Wembley Friendly’ in which Nigeria impressed but lost 0-1 to England’s Three Lions. NFF General Secretary, Dr. Mohammed Sanusi, who was on his way to Amodu’s home –town Okpella with NFF’s assistant director (technical) Abdulrafiu Yusuf and head of psychology Robinson Okosun for the burial on Saturday, said “This is most shocking. We are yet to recover from the death of Stephen Keshi.” Pinnick, who was on his way back to Benin City only 24 hours after returning from visiting late Keshi’s family, could only add: “Amodu’s name was synonymous with the Super Eagles. You can’t talk about the history of Super Eagles without Amodu getting prominent chapters
