High Voltage Testers

High voltage (HV) testers are used to detect, measure, or verify the presence of electricity in systems operating above 1000V AC or 1500V DC. It is used in substation, power lines, and industrial equipment. They are used for safety reasons by confirming if a circuit is live or dead, using contact, proximity, or insulation testing methods.

    High Voltage Insulation Tester | S-36 VLF

    High Voltage Insulation Tester - Overview

    The S-36VLF high-voltage insulation tester is a compact, robust and portable kit for testing medium voltage cables according to IEEE400, IEC 60502-2, CENELEC HD 620 and 621 and DIN VDE 0276/620 and 621. The test is carried out using the low electrical stress method, with a VLF (Very Low Frequency) voltage of 0.1 Hz. The VLF test is the fastest way to detect insulation damage. The S-36VLF instrument can test cables with plastic insulation (XLPE, PE-, EPR) as well as paper and oil insulation (PILC). Testing with DC voltage is also possible.
