IS RTCC AND OLTC REQUIRED FOR 500 KVA 11KV/433V TRANSFORMER
FOR AN INDUSTRY?
Answer Posted / kiran
there is no compulsury requirement that your transformer
with for OLTC & RTCC. Its depend on lot of condition that,
If u want supply withot interruption of line then u
required to used OLTC. Our substation transformer in MVA
rating & it has OLTC & RTCC hence there is does not
required OLTC for 500 KVA DTC. Feeder voltage controlled by
Substation person.
