what parameters should we check to reduce the power bill
If we have use two power cable for incomer, that time how many use cbct for earth leakage protection? 1 or 2 if 1 way? If 2 way?
Is it possible to measure correct value of earth resistance & cable insulation ristance with out disconncting earth lead & both sides of cable ends? If not, any other method to measure ER & CIR with out disconneting from the system.
what are the basic insulation levels & what its Unit
In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
if we have a industrial load of 400 kilowatts with 415 volt AC then how much total harmonic distortion (thd%) should be acceptable for steady power system.

Explain the method to keep noises low in a control system?
current transformer balance the power level on both sides. e.g in case of step up, at secondary side voltage rise but current decrease and vice versa in case of step down transformer. but how this power level remains same in case of current transformer and voltage transformer
Can anyone explain me about the capacitor calculation
How to do cable earhing? whether by grounding Armour to ground or by running extra G.I wire along with cable? which one is preferred mostly amoung them? If the second one is more preferable how many GI wires to be run along with cable (1 or 2)?
