An overview,

As one of the main equipment in power supply network, the working state of power transformer is related to the operation of the whole power supply network. As an important part of transformer, the working status of on-load voltage regulating switch will directly affect the running status of transformer. Developed by our company ZY2000 type load switch parameter tester, used the new testing principle, using microcomputer technology, make on site without having to remove the transformer and lifting switch, can the various performance of the power transformer on-load switch test, display and print the transition process of waveform and its parameters, is very convenient to judge the merits of the switch.

Two, technical indicators
