SXYZ-I Metal Oxide Arrester Tester is applied to measure and analyze the leakage current of MOA. Main purpose is to measure the resistive current to check the health of Metal Oxide Arresters, It can detect dangerous problems inside the arresters such as insulation moisture and valve plate aging.
♦ Advanced microcomputer controlling centre, safe and reliable.
♦ Adopts special weak signal sensor, to isolate against test MOA.
♦ Large LCD screen.
♦ To analyze and save the first 20 times test results, easy to operate.
♦ Built-in printer.
