80 * 80mm Round Type AC Insulation Resistance Meter With Relay Alarm
1. Products Introduction:
This type of meters are analog electric measuring instruments, widely used for measuring AC/DC current, voltage, frequency, power, power factor, insulation resistance and synchronous indicating in AC/DC transmitting & distributing power system, switchboard, other electric & non-electric instruments.
2. Using Instructions:
Monitoring the insulation resistance of ungrounded power network. When insulation resistance is lower than the preset value, alarm release.
Based on principle method, the net insulation monitor can be divided into following catagories:
a) . Monitor with measuring system, called integrated net insulation monitor, can be customized with self-dection function.
b). Monitor and measuring system are separated, called separated net insulation monitor.
c). Monitor the insulation resistance of two ungrounded power network at the same time, using integrated double circuit net insulation monitor.
