More efficient relay testing! This single unit supports testing of 4 voltage elements and 4 current elements.
The protection relay tester "RX4744" has achieved testing of voltage 4 elements and current 4 elements in a single unit, which previously required multiple models. Its compact and lightweight design allows it to be used for maintenance and inspection of core systems, as well as for testing protection functions related to mega solar, wind power, and cogeneration. To improve the efficiency of work at electrical equipment maintenance sites and the manufacturing of protection relays, it is equipped with various operating modes for individual and comprehensive testing, enhancing operability. By combining peripheral devices and software, it is possible to build an automated relay testing system. 【Features】 ■ Equipped with microcurrent output in the 400mA/5mA range ■ High accuracy in amplitude, phase, and frequency output ■ Built-in counter (milliseconds) allows for measurement of operating time ■ Rich operating modes for individual and comprehensive testing ■ Supports comprehensive testing by combining with a three-phase simulated circuit breaker with output switching function ■ Supports automation and efficiency of testing with protection relay testing software *For more details, please refer to the PDF document or feel free to contact us.
