How to calculate the efficiency of Turbo Generator(Alternator) in general....?
why we use copper earthing for neutral while for body GI.
Why Transformer Neutral having one earth pit ( more earth electrode resistance) whereas body have many earth pit ( less earth electrode resistance)?
Consider three heater bank connected in 3 phase star with neutral.Each heater bank connected in each phase.So each phase get 230 volts supply.my question is,during balance condition, current flow in neutral or Not
why the earth is taken minimum in supplying? wather it the proportional factor to getting work any equipment or a power plant?

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill. Q: Identify the appropriate solution you want to offer to Client?.Justify SCIENTIFICALLY and MATHEMATICALLY the principles behind the solution.
