Product Details

Direct sales of microcomputer relay protection tester

Function and Purpose

Can handle various relays(Such as current, voltage, inverse time limit, power, direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc)It can be calibrated with microcomputer protection and simulate various complex instantaneous and conversion faults for whole group testing.

Technical Features

1. Flexible combination of voltage and current output: The relay protection tester has a standard 4-phase voltage and 3-phase current output, which can easily perform various combination outputs for various types of protection tests. Each phase voltage can output 120V, and the current can output 120A in three parallel. The fourth phase voltage Ux is a multifunctional voltage item that can be set to four types of 3Uo or detect the same voltage, or output any voltage value.

2. Easy standalone operation: The device panel is equipped with a flexible photoelectric trackball mouse for operation through a large LCD screen, all displayed in Chinese. It can complete most of the on-site testing and verification work, verify various relays and microcomputer protections, and simulate various complex transients、Perform a complete set of tests for transitional faults. Ready to use upon startup, easy and fast to operate.

3. Dual operation mode, connected to a computer for operation: Through the full set of Chinese operating software on the Windows platform, various large-scale, complex, and highly automated verification tasks can be performed. It is convenient to test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.

4. Software Function *: The relay protection tester can complete various large-scale and complex calibration tasks with high automation, such as three-phase differential testing, plant power fast switching, backup automatic switching testing, line protection check synchronous reclosing, etc. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online.

5. Rich switch contacts with 10 input contacts and 8 pairs of output contacts. The input contacts are compatible with both empty contacts and 0~250V potential contacts, and can be intelligently and automatically recognized. The input and output contacts can be expanded according to user needs.

6. The large screen display adopts the Windows operating system, with a 10.4-inch large color screen. All operation processes are set on the display screen, and the operation interface and test results are displayed in Chinese, making the display intuitive and clear.

7. Self protection adopts a reasonably designed heat dissipation structure, and has reliable multiple protection measures, as well as power soft start and certain fault self diagnosis and locking functions.

8. There is an independent dedicated DC power output device with one 110V and 220V dedicated adjustable DC power output.

9. High cost-effectiveness belongs to cross disciplinary joint design products, which integrate multiple professional technological achievements. Combining the performance of a large testing instrument with the price of a small testing instrument, it has a high cost performance ratio.

10. The lightweight, compact, highly integrated single machine and integrated structure adopt a large number of high-tech and carefully designed ultra lightweight structures, making the whole machine extremely small and lightweight.
