1 3539we have read that when the piston goes up and down then the engine works i.e. the suction,compression etc etc. then what happens in the case of big vehicles, which start at stable condition, i.e. how does their piston moves when they are at rest. how suction,compression etc
Bhel,
5 6007why there is no current in the rotor body althrough the flux linking with it also get changes. why current only flows in windinds not in rotor
1 4561why we use condenser in the thermal power plant, althrough the same vapour will be again heated
Bhel,
1664WHEN SINGLE PHASE SUPPLY AS 220V, WHY THE 3 PHASE- 4 WIRE MEASURED AS 440 VOLTS INSTEAD OF 660 VOLTS (220 VOLTS PER PHASE i.e 220x3 = 660 volts ).
1 5571In case of salient pole alternator when number of poles are 4 or more than 4 it helps the flux wave to be sinusoid as air gap length is increased from center to tip , but if the number of poles are 2 how does the flux wave is sinusoidal?

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
