KGJB-703 Secondary Injection Testing Equipment 4 Phase Substation Relay Protection Test Set
Feature
1.The standard 4 phase voltage 3 phase current output has 4 phase voltage 3 phase current output, which can be easily carried out for various types of protection tests. Each phase voltage can output 120V, current three and can output 120A, the fourth phase voltage Ux is a multi-function voltage item, can be set to 4 kinds of 3U0 or detection voltage, or any voltage value of the case output.
2.Single machine easy to operate Single machine by the convenient and flexible rotating mouse through the large screen LCD display, all Chinese display. It can complete most of the field test and verification work, can verify all kinds of relays and microcomputer protection, and can simulate all kinds of complex transient, permanent and transformational faults for whole group tests. Boot can be used, easy to operate.
3.Double operation mode, connect the computer to run through the full set of Chinese operating software on the Windows platform, can carry out a variety of large complex and more automated verification work, can easily test and scan a variety of protection set values, can store test data in real time, display vector graphics, draw fault waveform, online printing reports, etc.
