how to understand the controling circuits example star- delta-starter controling daigram please let me know
i 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 firstname.lastname@example.org
Is C.T will sense the current in both direction. As i know the C.T will sense the current in only one direction.2 4793
Why the cost of CT increases with the decreasing of its CT Ratio (Technical Reason)?2 4827
How the size of transformer decreases if we increases the frequency?2 4353
how to synchronize 3 phase slip ring induction motors of different ratings.
can we use existing delta star with neutral grounded,step down(6.6kV/415V), 3 phase power transformer bi-directionally.
want happens when a dc is given to a commutator2 3772
A 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 5419
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?
What are the advantages of the three-phase motor over single phase motor?
Brief me about maintenance planning & sheduling of machine tool.
How line capacitance & line inductance varies with increase in height tower.
State and define norton’s theorem?
Will any motor burn if voltage provided is lesser than the rated voltage???? If yes, then how is speed control possible with voltage control
what is the difference between electrical choke and electronic choke?
