Product Details

■ Product Overview

The AC and DC voltage and current sources inside the single-phase relay protection comprehensive tester employ the latest power‑supply technology. , It facilitates the use of power‑supply instrumentation by on‑site personnel for other experiments; while maintaining simplified operation, this relay protection tester enhances the instrument’s functionality. , It can perform comprehensive tests on a wide range of common relays, and its meticulously designed front panel ensures intuitive, user-friendly operation, earning widespread acclaim from users.

■ 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.
