Professional Insulation Resistance (IR) Testing Solutions for Safe & Reliable Electrical Systems

Insulation Resistance (IR) Testing is one of the most important preventive electrical tests used to evaluate the condition of insulation in electrical equipment and power systems. It helps detect insulation deterioration, moisture ingress, contamination, aging, and potential electrical failures before they cause equipment damage or unexpected shutdowns.

Electromech Technology is a trusted provider of IR Testing Services in India, offering accurate insulation resistance testing, electrical diagnostics, preventive maintenance, testing & commissioning, and safety inspections for industrial plants, commercial buildings, substations, power plants, renewable energy projects, and utility installations.

As a Government Licensed Electrical Contractor, we specialize in Insulation Resistance Testing (IR Testing), Megger Testing, Transformer Testing, Cable Testing, Motor Testing, Generator Testing, HT & LT Panel Testing, Electrical Safety Audits, Testing & Commissioning, and Turnkey Electrical Projects across India.

What is IR Testing?

IR Testing (Insulation Resistance Testing) is a diagnostic electrical test that measures the resistance offered by insulation materials against leakage current. A high insulation resistance value indicates healthy insulation, while a low value may indicate deterioration, moisture, contamination, or insulation failure.
