I have 200 KVA Isolation Transformer for UPS input side. & ups was having 48% load, suddenly got short what will be the reason.
1 2902i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….
1 3885I have a 33 KV sub stn with two mother transformers 33/11 KV of capacity 3150 and 1600 KVA respectively. The total connected load 16809 KVA(11/0.433KV).how i calculate the max current & how i decided the CMD.
2 3374HOW TO SIZE THE TRANSFORMER OR WHAT ARE THE STEPS INVOLVED IN FINDING THE SIZE OF THE TRANSFORMER FOR GIVEN LOAD SAY 2000KW ?
1 3561If two transformers same rating(11KV / 440V)connected in the same primary line(11KV), can we connect(bus coupler) secondary side directly or need a synchronization????
3 11761what is the maximum rating(KVA) of transformer can be used in distribution side..(11KV/440v) and why??
1 4429how the transformer stables out zone faults? Because we use non directional O/C relays .Is there any special considerations are taking into account to overtake this?
1 2979why the desirable efficiency for a motor is 60%, but in case of transformer, it is above 90%?
1 3962For 6600/433 distribution transformer we apply secondary side 433 volts how much voltage in primary side.
