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.)

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.”
