Numerical Digital Voltage Relay With USB

PNVNSP range of relays provide reliable and high
performance protection.
The PNVNSP is a relay for AC Voltage supervision with
universal application, it protects the three phase network
against over, under voltage, unbalance or earth faults in
isolated networks. Beside the pure RMS value measurement
of the line voltage the PNVNSP evaluates the symmetrical
components (U1, U2 & U0 sequence system). By evaluating
these components relay PNVNSP can detect the phase
sequence, voltage unbalance and earth faults.
