product description

YD zinc oxide arrester tester is a special instrument for field and laboratory testing of electrical parameters related to lightning arrester. It is widely used in the field monitoring (live test) and laboratory (power failure maintenance) of zinc oxide arrester. The People's Republic of China power industry standard "DL474.5-92 site insulation test implementation guidelines - arrester test" to the number of the instrument using microcomputer for sampling, control and other advanced technology, can measure the zinc oxide arrester in the power frequency of the whole Current, third harmonic, resistive current, resistive current peak, capacitive current, active power, etc. and display voltage, current waveform and print output. Using large-screen LCD display, Chinese menu prompt operation, the man-machine exchange function More powerful. At the same time to provide on-site wiring display. The instrument has a simple wiring, high precision, reliability and other characteristics.
