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.
Answer Posted / sarthak
VCB must be installed as you are using quite a good capacity transformer.
Which needs better protection and the VCB at the sub station will not be that helpful ,
if ever you need to do maintainence job on your t/f you task will become easy.
