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 31751500Ah 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?
1732The 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.
