96*96mm Insulation Monitor Customized With Self - Detection System
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.
Explaination as follows:
"Monitor" mode: Ordinary monitoring, monitor works as normal;
"Suspend" mode: Invalid, monitor does not check with the insulation
resistance of circuit, and pointer come to ∞;
"Test" mode: Self-detection. Monitor does not check with the
insulation resistance of circuit, pointer come to 0, alarm LED lit,
release activated.
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.
