1. Standard 4-phase voltage and 3-phase current output: with 4-phase voltage and 3-phase current output, various combination outputs can be conveniently carried out for various types of protection tests. Each phase voltage can output 120V, current three can output 120A, the fourth phase voltage Ux is a multi-function voltage item, can be set to 4 kinds of 3U0 or check the synchronization voltage, or any certain voltage value.
2. Convenient stand-alone operation: The stand-alone machine is operated by a convenient and flexible rotary mouse through a large-screen LCD display, all in English. It can complete most of the field test verification work, can verify various relays and microcomputer protection, and can simulate a variety of complex transient, permanent, and transitional faults for the entire set of tests. It can be used after starting up, and the operation is convenient and fast.
3. Double operation mode, connected to the computer to run: Through a full set of English operation software on the Windows platform, it can carry out various large-scale complex and highly automated verification work, can easily test and scan various protection settings, and can be real-time store test data, display vector graphics, draw fault waveforms, print reports online, etc.
4. Powerful software function: It can complete all kinds of large-scale and complicated calibration work with high degree of automation, such as three-phase differential test, factory power cut, standby auto-switching test, line protection inspection and reclosing at the same time, etc., can easily test and Scan various protection settings, perform fault playback, store test data in real time, display vector diagrams, print online reports, etc.
