what happen if one of 3-phase line has a much higher load when we are using delta to star transfor..

Answer / sb

Upto certain extent it is allowable but beyond that O/C
relay may trip the circuit.
As said by the above friend abnormal neutral current will
flow & hence through the CT sec side & will actuate the relay.

Due to it system will be unbalance hence there will be some
neutral current .now if neutral of sta load is not grounded
then there will be harmonics ingection in the line which
will give poor performance of equipment used at load ide.

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 ?
