1. The whole current, resistive current and its harmonic, active power and phase difference of Zinc oxide surge arrester can be measured.
2. Large screen can show the true waveform of voltage and current. Instrument has digital waveform analysis technology, harmonic analysis and digital filtering, etc.
3. Software anti-interference method makes the measurement result accurate and stable, can accurately analyze the content of the fundamental wave and 3 ~ 7 times harmonic, and can overcome the influence of the interphase wave, and correctly measure the resistance current of the side surge arrester.
4. Truly three-phase simultaneous testing, but also to achieve a single phase test.
5. Can realize the wired mode, the wireless mode, the non voltage pattern test, can satisfy the test under the different environment different condition.
