3 5380A three phase transformer 460v primary 220v secondary (three phase four wire system.) Why did we get 460 volts across the neutral on the secondary side?
3 6003I 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?
