Features

Numerical Unbalance Voltage Relay JNV 026
  • Software based design
  • Trips on neutral snap
  • Programmable Active / Inhibit facility
  • Programmable Rated voltages
  • Wide range of time delay setting

Principle of Operation:

JNV 026 measures and displays 3 phase voltages (R,Y,B phases). It calculates percentage of unbalance voltage and if it exceeds the set unbalance voltage, the relay operates after the elapse of operating time. Under voltage fault will be detected when voltage on any phase is less than the set Under voltage limit, the relay operates after elapse of under voltage operating time. Over voltage fault is detected when voltage on any phase is more than the set Over voltage limit, the relay operates after elapse of over voltage operating time. Neutral snap will be detected when Neutral is disconnected.

Application:

JNV 026 is a numerical unbalance voltage relay, with under voltage(UV), over voltage(OV) and Neutral snap which is used for three phase systems etc.,
