HT breaker means on and off switch for HT voltage 11kv,33kv,....VCB,SF6 its HT breakers. HT breakers installed between consumer HT YARD and transformer.Reason for installed ht breakers any problem in case for transformer burning or transformer oil temperature, transformer winding temperature value,short circuit immediately commend process going to HT breakers then tripped HT breakers.HT voltage for 11000,33000,22000,...voltage so breakers on and off time over spark coming this spark reducing purpose vacuum,sf6 gas HT breakers particularly used. YOUR NOT USED HT BREAKERS handled not for easy in transformer and LT side all electrical equipment and HT side electrical parameter noted not for easy HT voltage, amps, kwh, kva,power factor, kvar,setting for sanctioned demand, alarm relay. setting.
