1.The standard 4-phase voltage and 3-phase current output. The machine has 4-phase voltage and 3-phase current output, which can easily carry out various combined outputs and various types of protection tests. The voltage of each phase can output 120V, and the current of three phases can output 120A. The voltage UX of the 4th phase is a multi-functional voltage item, which can be set to 4 kinds of 3 U0 or check the synchronous voltage, or output under the condition of any certain voltage value.
2.The single machine is operated by the convenient and flexible rotating mouse through the large screen LCD, and all are displayed in Chinese. It can complete most of the on-site test and verification work, verify various relays and microcomputer protection, and simulate various complex transient, permanent and conversion faults for the whole group of tests. It can be used after startup, and the operation is convenient and fast.
3.Dual operation mode, which can be connected to the computer for operation, through the full set of Chinese operation software on the windows platform, it can carry out various large-scale, complex and more automatic verification work, conveniently test and scan various protection settings, store test data in real time, display vector diagram, draw fault waveform, print report online, etc.
4.The software has powerful functions can complete various large-scale and complex calibration work with high degree of automation, such as three-phase differential test, auxiliary power fast switching, standby automatic switching test, line
protection inspection and synchronous reclosing. It can easily test and scan various protection settings, perform fault
playback, store test data in real time, display vector diagram, print report online, etc.
5. Abundant switching contacts The relay protection tester has 8-way contact input and 4 pairs of empty contact output. The input contact is empty contact, compatible with 0 ~ 250V potential contact, and can be identified intelligently and automatically.Input and output contacts can be expanded according to user needs.
6. The large LCD screen adopt 320 × 240 dot matrix large screen high-resolution graphic LCD, all operation processes are set on the display, and the operation interface and test results are displayed in Chinese, which is intuitive and clear.
7. Self protection adopts a reasonably designed heat dissipation structure, and has reliable and perfect multiple protection measures, soft start of power supply, and certain fault self diagnosis and locking functions.
8. Independent special DC power output with one circuit of 110V and 220V special adjustable DC power output.
9. High cost performance. It is a product designed jointly by multiple disciplines and integrates the advanced scientific and technological achievements of multiple disciplines. It has both the performance of large-scale tester and the price of small tester, and has a high performance price ratio.
