Transfer Switching
Transfer Switching
(OP)
Hi,
I`m looking for any code on transfer switching. I have a distribution board which is powered by two different incoming sources through two 22 k V/ 415 V transformers. The board is powered by any one source at a time. Transfer is actually done manually by operating personnel. Now the process people are pushing us to automate the switching. There is no mechanical interlocking on either MV or LV breakers but they are provided with shunt tripping. There is no possibilty to parallel the two sources because the transformers have different vector group.
