■ Product Features
This relay protection tester can perform verification on the following types of relays or grouped protection schemes:
Measurement relay : Includes current- and voltage-type relays, with the capability to measure their operating values, reset values, and operating ratios.
Time relay : Its pickup value, return value, and operating time can be measured, with a time measurement error not exceeding 0.2ms。
Intermediate relay : Verification of various intermediate relays equipped with both a start coil and a hold‑in coil enables measurement of the pickup value, reset value, holding value, and operating time.
Reclosing relay : It can perform capacitor charging tests, measure charging time, reclosing time, and test intermediate components.
Differential relay : It can perform DC excitation experiments, braking characteristic experiments, and volt-ampere characteristic experiments.
Other types of relays are uncommon.
