Measuring Insulation Resistance:

• The primary function is to measure the resistance of insulating materials (typically in ohms or megaohms, MΩ) in electrical systems. High resistance values indicate good insulation, while low resistance values suggest potential issues, such as insulation wear or moisture ingress.

Testing Cables, Wires, and Equipment:

• These testers are used to check the insulation resistance of cables, electrical motors, generators, transformers, switchgear, and other electrical equipment to ensure that they are properly insulated and safe to operate.

Detecting Leakage Currents:

• An insulation resistance tester can identify any leakage currents that flow through the insulation material, which could indicate damage or degradation of the insulation, posing safety risks.

Testing in Different Voltage Ranges:

• Many insulation resistance testers provide the ability to perform tests at different test voltages (e.g., 250V, 500V, 1000V, and sometimes higher). The test voltage used depends on the type of equipment being tested. Higher test voltages are typically used for testing larger electrical systems like transformers or generators.
