  • Product Introduction

ZC-220 transformer on load tap changer tester is mainly used to measure the transition waveform, transition time, instantaneous transition resistance value, three-phase synchronization, etc. of transformer on load tap changer. The instrument has small volume, light weight and strong anti-interference ability, which greatly reduces the labor intensity of on-site staff. It is an ideal instrument for power generation and power supply units and transformer manufacturing industry to ensure safe production and improve product quality.
