Insulation Resistance Testing

Insulation Resistance Testing evaluates the integrity of electrical insulation in switchgear components to prevent leakage currents, short circuits, and electrical faults. This test ensures reliable operation, extends equipment life, and maintains safety in industrial and utility electrical systems.

Accurate Insulation Assessment

Measures resistance levels to detect insulation deterioration, moisture ingress, or contamination.

Suitable for Various Switchgear Equipment

Applicable to circuit breakers, transformers, cables, busbars, and motor windings.

Preventive Maintenance Essential

Early identification of insulation issues reduces downtime and costly repairs.

Detailed Test Reports

Provides comprehensive documentation with resistance values, trends, and maintenance advice.

End-to-End Insulation Resistance Testing Process

Reliable Evaluation of Electrical Insulation Health

Equipment Preparation & Safety Precautions

Isolate the switchgear and discharge stored energy to ensure safe testing.

Step 01

Test Setup & Calibration

Connect insulation resistance testers (megohmmeters) and verify calibration.

Step 02

Conduct Resistance Measurements

Apply test voltage and record insulation resistance at defined intervals.

Step 03

Result Analysis & Reporting

Interpret resistance values, assess insulation health, and provide maintenance recommendations.
