If one d.g. is unable to take full load of system, then second d.g. will take care of partly Load.for this condition RPM of both DG set should be equal.By using Synchronization panel RPM of dg sets are match, is it true?
1 38451500Ah VRLA battery,if its weight is designed 125kg during maufacturing its weight is reduced to 85kgs,What will be impact on AH capacity,life & economy?
2176The capacity of the transformer is 20/25 MVA, Ratio is 132/11 KV, Vactor group YNyno. and impedance is 10.07%. As per the calculation the secondary current is 1312.2Amps. The maximum fault current the transformer should sustain is 13.030KA. How many times the transformer should sustain the maximum short circuit current of 13.030KA over a period up 1 Year. The transformer is repaired one & 10 Years old.
1 9378Why in Digital Megger for finding Insulation resistance,-ve is applied to core or conductor and +ve is applied to ground.

EXPLAIN WHY THE SURGE CURRENT RATING OF AN MCCB OR CIRCUIT BREAKER DECREASES WITH INCREASE IN THE RATING OF MCCB OR CIRCUIT BREAKER.
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.???? My Whats app No:07621840498 for Further Discussion. Pls experts suggest.
