Product Description

single phase secondary injection test kit three phase  secondary current  injection relay tester set 

I. Overview
Relay protection tester is significant instrument of calibration and commissioning used for relay protection circuit and instrument of power generation, supply and consumption equipments in the power system and large plant and mining enterprises.
This instrument is composed of digital millisecond meter with fully-isolating dual channels and long time counting, large power AC and DC voltage, current output unit, high-precision multifunctional AC/DC digital ammeter and voltmeter, and logic control, overload protection and signal display unit with very strong functions; adds the power frequency phase meter and automatic reclosing test function.
The two input channels of millisecond meter are provided with complete electric isolation, without considering common-ground short-circuiting during the test, and it is particularly suitable for online electrical testing of dynamic characteristics of the relay. This is not in common relay protection tester and millisecond meter. The dual-channel signal can be made with idle contact. Positive (negative) pulse, test power source, automatic synchronization signal and positive (negative) pulse width can meet the time characteristic test and whole-set test for various relays. The phase meter is more suitable for the testing of complex protection. All the measured values are displayed in digital manner, which are intuitive and precise. This relay is a new-generation tool for protection checking.
