1.“Built-in industrial control computer + 10.4-inch touch screen”, supporting offline operation and having a small size providing ease of carriage;

2. 4 *125V voltage + 6 *35A current power amplifier outputs. Output can be realized in all voltage and current phases in an on-load manner;

3.Support for up to 50 harmonic outputs and capability of superposing inter-harmonics with subharmonics facilitating the testing of such protective devices as DC high-voltage filter, etc.;

4.Multiple synchronous timing functions based on GPS, IRIG-B, IEEE-1588, etc.;

5.Built-in Wi-Fi access which is pioneered in China so that this tester can be controlled by a computer via a wireless network to greatly facilitate the operation by on-site personnel;

6.Simulation of electrical isolation between the current ground In and voltage ground Un of the output. Such simulation provides greater compliance with wiring requirements on the test field;

7.Abundant software testing functions so that line protection, bus protection, transformer protection, generator-transformer unit protection, etc. and spare power automatic switching device can be tested;

8.Support for replay of waveform data in the standard COMTRADE format;

9.The software can be upgraded to the latest version free of charge at any time without changing the hardware.
