Insulation Resistance Measurement Instrument

The Insulation Resistance Tester is specifically designed for laboratory or on-site insulation testing. It includes a high-precision microcurrent measurement system and a digital step-up system. Measurement can be conducted by simply connecting the test piece with one high-voltage line and one signal line. The measurement is automatic, and the results are displayed on a large LCD screen and stored.

I. Key Features

III. Operational Component Functions

 1.LTerminal Connector:“LFor the high-voltage output end, referred to as the line end, which is connected to the measured line end via high-voltage cables, such as to the motor winding or cable core.

 2.GTerminal Connector:“GThe shielded end, used for measuring the volume resistance of insulating materials or cables in the three-electrode method, is connected to the protective ring terminal of the three-electrode setup.

 3.ETerminal Connector:“E"Known as the earth terminal, it is connected to the ground or neutral point of the item being tested. For example, the metal shell of an electric motor, the iron core of a transformer, or the shielding layer of a cable."
