Wuhan Wugao Electric Measurement Co., Ltd

WDJB-702 Relay protection comprehensive tester (three-phase single-chip microcomputer)

The three-phase version software of the relay protection tester is a new generation of test software. Its characteristics are: the interface is more friendly and beautiful, the software functions are more complete and powerful, and its unique interface is simple and clear, easy to operate, easy to learn and use. . According to the different functions of each test module, the test modules are divided into five groups: general test, general protection, line protection, component protection and comprehensive functions, and each group contains several submenus.
