Profile:
It can complete various large-scale complex verification tasks with high automation level, such as three-phase differential test, plant power fast switching, backup automatic switching test, line protection check synchronous reclosing, etc. It can conveniently test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online.
Features:
1. The standard 4-phase voltage and 3-phase current output has a 4-phase voltage and 3-phase current output, which can be easily combined for various types of protection tests. Each phase voltage can output 300V, and the current can output 90A in three parallel. The fourth phase voltage Ux is a multifunctional voltage item that can be set to four types of 3U0 or output under the condition of detecting the same phase voltage or a certain voltage value.
2. Convenient single machine operation. The single machine is operated by a convenient and flexible photoelectric trackball mouse 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 complex instantaneous, permanent, and conversion faults for whole group testing. Ready to use upon startup, easy and fast to operate.
3. Dual operation mode, connected to a computer and running through Chinese operating software on the Windows platform, can perform various large-scale, complex, and highly automated verification tasks. It can easily test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.
