Double Structure Insulation Monitor , Insulation Resistance Monitor Moving Coil Structure
1. Quick Overview:
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.
Our 96*96mm & 72*72mm squre meter, and 110*110mm, 80*80mm are round type meter improved in structure, material, seals according to environmental conditions & demands in marine industry, which let our meter have the ability of not only advanced technology, reasonable structure, good quality, but also good appearance, light weight, anti-mechanical force and different climate.

5. 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.
