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.

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
