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 data reliability and safety.

Resistive Current Measurement Modes
There are three resistive current measurement modes: wired mode, wireless mode, and inductive mode.
Generally, wired mode is chosen for measurement to ensure accuracy. The other two modes are for reference use.
