Insulation Tester Calibration Services

Insulation testers apply a high-voltage, low-current DC charge to measure resistance in wires, cables, and motor windings. This helps detect leakage current and identify damaged or degraded insulation that could lead to arc faults, circuit failures, electric shocks, or fire hazards. Insulation resistance testing is crucial for ensuring safety, preventing short circuits, and maintaining equipment reliability. It is widely used across various sectors, including industrial facilities, commercial buildings, and residential properties, to protect both personnel and electrical systems.
