Protection Relays
NPU800 & NPU800R / NPU800RE – Voltage and Frequency Relay
Products family : Voltage Protection Sector : Industry, Railway NPU800 & NPU800R provide the voltage and frequency monitoring of electrical networks. These multi-function relays supervise phase to phase and phase to earth faults, positive, negative and zero sequence voltage and the good operating of the circuit breaker and its trip circuit. With its numerous under…
NPUH800 & NPUH800R – Residual Overvoltage Relay (Neutral Displacement Relay)
Products family : Feeder Protection, Voltage Protection Sector : Industry NPUH800 & NPUH800R provide the zero-sequence voltage monitoring of three-phase networks with isolated or high impedance earthed neutral. These multi-function relays supervise phase to phase and phase to earth faults and the good operating of the circuit breaker and its trip circuits. NPUH800R (R2 case)…
NPW800 & NPW800R – Power and Voltage Relay
Products family : Power Protection Sector : Industry NPW800 & NPW800R perform the measurement of the apparent (S), active (P) and reactive (Q) power of 3 or 4 wire electrical networks. The monitoring of the energy flow direction is completed by the management of power factor, tangent φ and by the supervision of network voltage…
AMS7001 / AMS7002 – Automation Measuring and Control Devices
Products family : Feeder Protection Sector : Industry The optimum operation of an electrical network depends particularly on the reliability and the availability of the protection, measuring and automation devices, and the way these devices can communicate their information. AMS 7000s provide the “automatic control” (AMS 7001) and “the automatic control and instrumentation” (AMS 7002)…
CMS7003 / CMS7004 – Instrumentation Devices
Products family : Feeder Protection Sector : Industry The optimum operation of an electrical network depends particularly on the reliability and the availability of the protection, measuring and automation devices, and the way these devices can communicate their information. CMS 7000s perform the “measurement” functions of the PROCOM system. Installed in the control room or…
