Our know-how in the domain of electrical network protection by static and numerical relays has led to the development of new generations of products that comply with the most demanding quality standards and the most recent technological concepts. One of the results of this expertise is the numerical NP800 relay range.
The NP800 relays provide the protection of people, networks and electric installations and they allow communication with SCADA systems. As well as the usual protection functions of former ranges, the multifunctional NP800 relays provide monitoring, measurement and recording of the network electrical quantities.

Common characteristics for the NP800 range:

• Auxiliary supply ranges: 19V to 70V or 85V to 255V (AC or DC)
• 2 setting tables
• Self-diagnosis: RAM, ROM, EEPROM, output relays, A/D converters, auxiliary supply, monitoring of software execution time
• Optional I/O extension board (included when directional function is present)
• Setting, reading, measuring and recording are all available locally or remotely
• Complies with IEC 60255-4 standard.
• Monitoring of circuit breaker failure
• Event recording: 250 events, 10ms resolution
• 4 disturbance recordings in COMTRADE format
