SMR635/SMR635A Insulation Resistance Tester, High Performance ARM Micro Processor Control Design
SMR635/SMR635A Insulation Resistance Tester
1.DESCRIPTION
An insulation resistance tester is an instrument used to measure
the insulation resistance of electrical insulation materials,
equipment, or circuits. It is mainly used to detect the integrity
of the insulation system, evaluate the insulation performance, and
identify potential insulation faults.
The working principle of the insulation resistance tester is based
on Ohm's law. By applying a DC voltage to the insulation system
under test and measuring the leakage current passing through the
insulation system, the insulation resistance value can be
calculated. The insulation resistance value is usually expressed in
megaohms (MΩ).
