Fault Location in High Voltage Shunt Capacitor Banks
… With today’s sensitive protection available in numerical relays these failures will be detected and SCBs will be taken out of service. But determining the phase and section in which capacitor elements have failed is important for utilities to decrease downtime of SCBs. This thesis proposes …

ACCELERATED ZONE-2 TRIP ALGORITHM FOR A NON-PILOT DISTANCE RELAY
Distance relays use time stepped protection zones for coordination purposes. The time delay introduced by zone-2 distance relays limits the use of these devices for extra high voltage (EHV) applications since the fast fault clearance requirement is not achieved. Transmission lines are normally …
