Why Us!
HT panel provides protection also from various
faults (depending on the fault protection relays installed in the
panel). When fault occurs in the system HT panel is switched off
automatically (this process is also known as tripping). Each relay gives
fault indication when it operates. Before switching on HT supply again,
fault should be identified & rectified. If fault persists in the system,
then relay will not be reset & HT panel can’t be switched on because of
interlocking between relay & panel. Therefore, it is very important to
clear the fault first & then switch on HT supply again. (Note- Relay
should not be bypassed for any reason).
