Engineering AllOther (1379) We have a 1275KVA existing Transformer in a power plant project. Customer want to get it test & confirm whether it is a Dyn1 Transformer or not. Pleae let me know how to test it.
1 3964why Transformers power mentioned in KVA?. and why Generators and Motors power mentioned in KW?.
10 14517What is the purpose of Rotor earth fault relay and How to test the Rotor earth fault relay in generators and What is the procedure?.
1 4416we 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 7580why 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 5416why we use condenser in the thermal power plant, althrough the same vapour will be again heated
Bhel,
2164WHEN 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 6373In 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?
