What is the tests required for a 132 kV, 400 kV , 765 kV for a Circuit Breaker and Power Transformer before commissioning ?
1531Question 58 – In the design of a solar power system steps of calculations below are followed : (a) The power output of the inverter of the of the solar panel is 100 watts. What is the power input, Pin to the inverter when the efficiency of the inverter is 50 %? (b) If the rated power of the inverter is 300 watts, how many inverter is needed for the solar panel? (c) Charge controller of V = 12 volts is used to supply power to the inverter. What is the input current I to the inverter? (d) If the charge controller capacity is 10 A, how many charge controllers are needed? (e) If a biochemical mixer consumes 100 watts, running for 2 hours per day, what is the energy consumption in kilowatt hour per day? (f) What is the input energy needed when the efficiency of the inverter is 50 %? (g) If your area receives 2.88 hours of full sunlight per day, how much energy, in kilowatt hour can be produced per day when one solar panel can produce 20 watts of power? (h) If you know that you have to produce total energy as the answer for (f), how many solar panels are needed? (i) Each V = 12 V battery has 5 ampere hours. If the total energy needed is in answer (f), then how many batteries are needed to run the biochemical mixer if without sunlight for 3 days?
1 2412If you were given a chance to become a mayor or someone who has power and authority over all the country what would you like to do and why?
2273typically in power distribution substation. 1- Any idea how would be the graph of capacitor bank consumption verses time through the day . 2- How is the switching ( on and off ) of the capacitor bank, per need?
1695what is power factor ? how we can calculate the low power factor and amount of capacitor for improve that low factor ?
1579I have 30 kw motor load & i have selected 10 kvar capacitor bank for power factor improvement.my existing p.f is 0.85 & proposed p.f is 0.99 so ,is it right selection? 2 nd question how to connect c.bank whether in delta or star connection & how to decide it?

Is it possible to do load testing in POWERMHS? If yes how do you do that?
Hi friends Does anyone have screen shot of POWERMHS and please can anyone post anything which will be helpful to understand POWERMHS. thanks.
what is the day to day work of SAP FICO Consultant. which are the documents,white papers he uses. who will assign him work and in what form, is it a flowchart,word document,power point presentation ?and also what is business blue print and how it is documented(word,flow chart),?? please answer my question

how can we Upgrad the reports from version Impromptu 6.0 to 7.0 and Power Play from version 6.6 to 7.0 ?
why should we choose VSTET(Visual Studio Team Edition for Testers) and not QTP?pleas give me the reasons for "WHY" we have web and client server app, supports power builder and on windows OS so this is the background of tech and envir things we have and now VSTET is good to use or not? if "NO" then tell me why
I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
