insulation testers
What is insulation testers?
Insulation testers, also known as megohmmeters or insulation resistance testers, are instruments used to measure the insulation resistance of electrical equipment and wiring. They apply a high DC voltage (typically ranging from 50V to 5kV) to the insulation and measure the resulting leakage current. This allows assessment of the quality and integrity of the insulation. Common applications include testing motors, cables, transformers, and switchgear to detect insulation degradation, potential faults, and ensure electrical safety.
