WebApr 15, 2024 · The CB must be in healthy condition. If the CB unhealthy status is received by the AR relay it will block the AR function. If the fault detects in SOTF or Zone 3 or Zone 4, in that case, the relay will block the AR function. Lockout mode (AR Lockout) Lockout mode is the important function in the Auto reclose relay.

รีเลย์ (Relay) คืออะไร?
WebDistance relay applications. Distance relays respond to the voltage and current, i.e., the impedance, at the relay location. The impedance per mile is fairly constant so these relays respond to the distance between the relay location and the fault location. As the power systems become more complex and the fault current varies with changes in ... WebThe master trip relay can operate as a hub of multiple protection relays trip commands and drive multiple subsequent contacts. This makes the relay a protagonist to execute simultaneous commands like breaker trips, interlocks, alarms, data display, SCADA extensions, and lockouts.
