how to understand the controling circuits example star- delta-starter controling daigram please let me know
GMR,
3 7018i am electrical and elctronics engg passed out in 2009 want to attend for reliance placements.plz send me apttitude ,technical and hr question answers to my mail plz. my mail id-kat.bindas@gmail.com
1486Is C.T will sense the current in both direction. As i know the C.T will sense the current in only one direction.
2 4793can we use existing delta star with neutral grounded,step down(6.6kV/415V), 3 phase power transformer bi-directionally.
GMR,
3 4835A 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 5419I 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?
