In addition to being able to calibrate various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, it can also simulate transient and conversion faults from single-phase to three-phase for whole group testing. It can also complete various highly automated large-scale complex verification tasks, automatically test and scan various protection settings, perform fault playback, test backup automatic switching, fast switching, system oscillation, etc., store test data in real time, display vector graphics, print reports online, etc. 6-phase current can facilitate three-phase differential protection testing, and 12 phase output can be used for backup automatic switching testing.

1. The standard 12 phase voltage and current are output simultaneously, and the amplitude, phase, and frequency are independently adjusted

2.12 Channel Closed loop Recording Monitoring is used to extract, monitor, and record the voltage and current output waveforms of the 12 channels of this machine. It can intuitively and conveniently monitor and observe the distortion of the output waveforms. The recording time is determined by the size of the hard disk capacity, and the recording files can be replayed during fault reproduction.

3. In addition to standalone operation, the device can also be connected to an external desktop or laptop for operation. The functions of the two methods are the same, providing a truly complete dual operation mode.
