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 and current with four elements each, which previously required multiple models, all in a single unit. Its compact and lightweight design makes it suitable for maintenance and inspection of core systems, as well as for testing protective functions related to mega solar, wind power, and cogeneration. To improve the efficiency of work in electrical equipment maintenance 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, an automatic relay testing system can be constructed. 【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 ■ Output switching function combined with a three-phase simulated circuit breaker to support comprehensive testing ■ 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.
