What are the characteristics of relay protection tester?

The 4-phase voltage and 3-phase current outputs of 1. standard have 4-phase voltage and 3-phase current outputs, which can be conveniently combined for various types of protection tests. Each phase voltage can output 120V, and three-phase current can output 120A. The voltage Ux of the fourth phase is a multifunctional voltage term, which can be set to four kinds of 3U0 or synchronous voltages, or any voltage value.

2. Single machine operation is simple. The stand-alone computer is operated by a large LCD screen and a convenient and flexible rotating mouse, all of which are displayed in Chinese. It can complete most of the field test verification work, verify all kinds of relays and microcomputer protection, and simulate all kinds of complex transient, permanent and switching faults for a complete set of tests. Can be conveniently and quickly opened and operated.

3. Dual-operation mode, connecting a computer to run a full set of Chinese operating software on the Windows platform, which can carry out various large-scale, complex and highly automated calibration work, facilitate testing and scanning of various protection settings, store test data in real time, display vector diagrams, draw fault waveforms and print reports online.

4. The software has powerful functions, and can complete various large-scale and complex calibration work with high automation, such as three-phase differential test, rapid switching of auxiliary power, standby automatic switching test, line protection inspection and synchronous reclosing. It can conveniently test and scan all kinds of protection settings, play back faults, store test data in real time, display vector diagrams, print reports online and so on.

5. The switch contacts have rich 7-way contact inputs and 2 pairs of empty contact outputs. The input contact is empty, compatible with 0 ~ 250 V potential contact, and can be intelligently and automatically identified. Input and output contacts can be expanded according to user's needs.

6. Large-screen LCD This machine adopted a 320×240 dot matrix large-screen high-resolution graphic LCD screen in the pilot test. All the operation processes are set on the display screen, and the operation interface and test results are displayed in Chinese, which is intuitive and clear.

7. Self-protection, with reasonable heat dissipation structure design, reliable and perfect protection measures and soft start of power supply, with certain fault self-diagnosis and locking functions.

8. Independent dedicated DC power output device, equipped with dedicated 1 10V and 220V adjustable DC power output.

9. It is a product designed jointly by many disciplines, which integrates the advanced scientific and technological achievements of many disciplines. It has the performance of a large testing machine.
