Handheld relay protection tester

1Product Introduction

HZJB-Z70Handheld relay protection testerSuitable for secondary operation, maintenance, and commissioning work of users such as power systems, power plants, mining and chemical enterprises, power transmission and transformation engineering companies, and relay protection instrument manufacturers.

IICharacteristics and main functions

1) Rich testing functions: ① General testing: manual testing, status sequence, automatic transition, harmonic, AC sampling, relay testing, small signal testing; ② Functional testing: compound voltage overcurrent, distance protection, zero sequence protection, low cycle load shedding, low voltage testing, synchronous testing.Handheld relay protection testerIt not only meets the testing requirements of protection and measurement devices for the main network and substations of 110kV and above in power plants, but also meets the testing requirements of terminal devices such as FTU, DTU, TTU in distribution networks.

2) The tester adopts advanced low-power circuit design, which not only reduces the heat generation of the whole machine, but also greatly improves the endurance. Under normal use conditions, the endurance can reach more than 8 hours.

3) The tester adopts unique digital electronic technology and power electronic technology to ensure high stable current and voltage output, smooth output waveform, high output accuracy up to 0.1%, and good stability.

4) The tester adopts an industrial grade 10 inch OLED touch screen for operation and display, with a good human-computer interaction interface, simple and easy to use, and fast testing.

5) The tester comes with overheat and overload protection functions to ensure the safety of users and the tested equipment.
