Answer / sakthivel

earth fault meant by,
when ever electri fault accur in appartus or machine or
network ,the fault curent does not dishcharge on ground
because the earth wire is not conected in ground.so this
fault is called earth fault

over current mean by,
when ever a electrical network or electrical circuits
have takes high current compare then its rated current
value this current called over current fault.

we use 3 phase supply for induction motor why not use two phase supply .

TRANAFORMER RATING 500 KVA,33KV/433, SECONDARY SIDE SWITCHED ON ONLY CAPACITOR LOAD 140 AMS, PRIMARY SIDE HOW MUCH VOLTS INCREASE?

I have two AC generators, the first rated 2680KVA for 380V/4345A/pf:0.7 and the second rated 3461KVA for 5500V/363A/pf:0.8. I want to parallel the two generator to a bus. The second generator passes through a transformer to down the voltage to 380V and a part of its power goes to another bus so that it's only a part of the total power of the second generator taht goes to the considered bus. I have two Basler DECS100 AVR regulator. How can I make the synchronization ? What others equipments must have ?
