  Voltage Transformer Error Detection Platform

  This product is an integrated device for voltage transformer error detection on site. It is mainly used to apply frequency voltage to various voltage transformers and measure the voltage error. It can be used to test the withstand voltage error of transformers at the substation or in the factory. It is currently the only voltage transformer error detection device in China that can achieve an altitude of less than 4500 meters. The product adopts the self-developed anti-seismic structure, which can meet the requirements of special transportation environments such as Tibet and Xinjiang, and the level of platform integration automation maintains domestic leading in China.
