    Functions
    The single-phase relay protection test equipment can test various AC/DC, current, voltage, intermediate, self-protection, signal and other single relays and the entire set of electromechanical protection screens.
    The secondary injection relay test kit can test the pull-in voltage (current) value of various relays and release the voltage (current) value.
    The Single phase protection relay test kit tests the pull-in and off-time of various contacts (normally open, normally closed, switched, delayed). It can easily test the parameters of the reclosing relay, and can replace the traditional stopwatch as a precision millimeter.

    Tips: Test of single-phase secondary injection tester for power system protection relay

    The relay protection tester is an important calibration and commissioning instrument for power generation, power supply and consumption equipment for relay protection circuits and power systems as well as for large power plants and mining companies.
    Single-phase relay equipment consists of a fully isolated dual channel and long time counting digital millisecond meter, high power AC and DC voltage, current output unit, high precision multi-function AC/DC digital ammeter and voltmeter and logic control, overload protection and signal The powerful display unit is combined with the power frequency phase meter and automatic reclosing test function.
    The two input channels of the millimeter meter have complete electrical isolation, and there is no need to consider the common short circuit during the test, especially for the dynamic characteristics of the online dynamic test relay. This is not a universal relay protection tester and a millisecond meter. Dual channel signals can be implemented with idle contacts. Positive (negative) pulse, test power supply, automatic sync signal and positive (negative) pulse width can meet the time characteristic test and complete set test of various relays. The phase meter is more suitable for testing complex protection. All measurements are displayed digitally, intuitive and accurate. This relay is a new generation of tools for protection inspection.
