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 3958why Transformers power mentioned in KVA?. and why Generators and Motors power mentioned in KW?.
10 14503What 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 4409why 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 5409why we use condenser in the thermal power plant, althrough the same vapour will be again heated
Bhel,
2156WHEN 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 6369In 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?

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
