Insulation Tester is a professional instrument developed and produced by HV HIPOT in accordance with IEC 61010-1 and other relevant standards. It is used to measure the insulation resistance of power transformers, cables, motors, lines and materials. It uses high-voltage DC injection technology to output a stable DC voltage to the device under test through an internal precision high-voltage generator, accurately measuring the leakage current and automatically calculating the insulation resistance value.
