High Voltage Insulation Tester

High voltage insulation testers are specialized electrical instruments used to evaluate the insulation resistance and withstand voltage capacity of electrical equipment, cables, and components under high voltage conditions. For industrial buyers and electrical system engineers, these testers are critical tools for ensuring safety, equipment reliability, and compliance with international electrical standards.

Working Principle:

High voltage insulation testers apply a controlled high voltage (typically between 1kV and 100kV) across an insulating material and measure the leakage current. The measured insulation resistance indicates whether the insulation is intact or degraded. In withstand voltage mode, the tester checks whether the insulation can sustain a high voltage for a specified duration without breakdown.
