WGB-55WGB-55C is a microcomputer protection device for medium and low voltage system developed by Relay Company of Xuji Electric Co., LTD. It is mainly used in the protection of high voltage switchgear with voltage level of 10kV and below. It can also be installed in a panel, and can protect equipment such as feeders and factory transformers. (These two protection devices collect analog current and analog voltage, and the protection function is basically the same, the difference between the two is that the WGB-55C has an anti-jump loop, and the WGB-55 does not have an anti-jump loop).
