I did oil BDV test of 1600 KVA trafo 20KV/400V as per IEC 156. Result is 1) 58 KV 2) 58 KV 3)40 KV 4) 50 KV 5) 58 KV 6) 18 KV. Avr is 47 KV. Can we say oil is still ok even in the 6th test BDV is 18 KV ?
can we use 7volt DC BATTERY to run a 60watt motor by stepup? Give reason for your answer?
We are installing a 1.6 MVA transformer at our crusher plant and the feeder of HPSEBL is 2 km away at substaion . and a VCB is installed in the substaion which is 2 km away from transformer so we need another VCB near the transformer.
