I have 12MW gas engine based power plant its running parallel
with grid. my problem is When cpp run in island mode(without
geb) that time geb transformer power factor is 0.2 lagging.
When cpp run with parallel that time power factor is 0.94 lagging
So how can i maintain power factor ofgeb transformer in island
mode 0.9 lagging?

I had been involved in similar scenary in a 1500 MT/D chamical plant where we operated in synchonized normal operation mode condition but in case of public electrical system disturbance due to severity storn, we were about to go into the islaned mode operation.
What we did was, to install an automatic power factor control (APFC) bank to put an end at this problem so we reach o.96 PF during islaned operation.
Bye

when meggering a 3ph,480v oil reservoir heater on a regen gas compressor, why do I get a reading to ground when meggering phase to ground? shouldn't it read opened or is there something that makes it read closed? on the same heater, when ohming, it reads open. thanx
which fault current is maximum: 3 phase short circuit, LG, LL or LLG?? why?? in one of the problems that i have solved, 3 phase short circuit current on an unloaded generator came out to be less than the LG fault current. can anybody please explain why.

in our 6.6kv motor feeder[it is having two sources from Bus A&B] earth fault relay is acting, we checked CBCT connection and cable meggerd values found very good still earth fault acting during first two are three start after that it will hold. please clarify what was the reason. if same motor is starting from other Bus-A it will start.
