Using digital waveform analysis technology, harmonic analysis, and digital filtering software anti-interference methods, the measurement results are accurate and stable. It can accurately analyze the content of the fundamental wave and the 3rd to 7th harmonics, and can overcome the influence of inter-phase interference to correctly measure the resistive current of side-phase arresters. Isolated digital sensors directly collect input voltage and current signals, ensuring the reliability and safety of data.
