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 2924why Transformers power mentioned in KVA?. and why Generators and Motors power mentioned in KW?.
10 10995What 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 3173why 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 4140why we use condenser in the thermal power plant, althrough the same vapour will be again heated
Bhel,
1502WHEN 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 5232In 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?
