Insulation Resistance Tester UT-502A


Category: Tag:


UT-502A insulation testers are used to measure the insulation resistance of electrical equipment and household appliances. This is done by measuring the insulation resistance between electrical circuits or between circuits and ground. UT-502A can measure insulation resistance, AC Voltage, low resistance, PI (Polarization Index) and DAR (Dielectric Absorption). This is ideal tools for ensuring transformers, genera-tors, high voltage motors, power capacitors, power cables, arresters and other electrical equipment that can operate in a safe and accurate manner.
