Does dry and oil transformers both require dedicated neutral, because in my project we are using 2500kv dry star delta transformer, where they say neutral not required and even it is not provided in our substation. can u let me know
2 3167What is the rating of circuit breaker needed for 300 KVA load in 33 KV supply line in a transformer of 33 KV / 415 Volt ?
1307What is the rating of a circuit breaker needed for 300 kv load in 33KV supply line of 33/415 transformer ? Whether 800/1200 amp vaccum circuit breaker can perform for a 33 KV line in input in 415 volt in output of the transformer ?
1231if a 2 ohm resistor,2 ohm capacitor and a 2 ohm inductor is connected parallely to 12v source.Then what is the value of current in each branch.Is current flows in each branch at the same time?If not so then provide the proper sequence
1 2310According to ohms law voltage proportional to current, then why should current rating is low with high voltage rating in transformer?

I am having a 42KW 3 phase electrical heating furnace, heating element is 80/20 nichrome material, my connections is made in such a way that 2 star connection compromising 2 coils per phase so totally 12 coils, shall if i use it unbalanced star condition (instead of 2 group of 3 phase or 1 group of 3 phase, connecting 4 phases of 5 phases) what will be the consequences and is it acceptable?
