NPW800R

Power protection

Our NPW800R (R3 case) is dedicated to the refurbishment of 7000 series relays.

It performs 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 and frequency.
