WebPrinciple of Differential Relaying is applied for instantaneous tripping for in zone faults Four wires, normally termed as Pilot Wires, run in between substations to compare current between terminals (Typical F/C 15ms 25ms) HCB Relays from Westinghouse (ABB) are predominantly used as Pilot relays for lines up to 20 miles. HCB relay contains ... Webthe type HCB relay on the, relay side of the insulating transformer, as shown in Figure 3. If the type HCB relay contacts have already closed due to the inrush, they will immediate ly reset when this short circuit is estab lished before tripping can be accomplished. It is the purpose of the type SG relay insert
