The XHDD405 wireless series live tester for zinc oxide arresters supports energized and non-energized detection for all voltage-class arresters. It helps identify critical defects such as internal insulation dampness and valve element aging at an early stage, reducing the risk of sudden arrester failures in service.
It can test total current, resistive current and harmonics, power frequency voltage and harmonics, active power and phase difference. The large screen displays real-time voltage and current waveforms, and precisely analyzes the fundamental wave and 3rd to 7th harmonics.
The XHDD405 measures the key electrical parameters that reflect the operating condition of zinc oxide surge arresters. The table below summarizes the measurement functions and their typical application scenarios:
| Measurement Function | What It Measures | Typical Application Scenarios |
|---|---|---|
| Total Current and Resistive Current | Total leakage current and its resistive component under working voltage | Assessing valve element aging and internal insulation dampness of MOA arresters |
| Harmonic Analysis | Fundamental wave and 3rd to 7th harmonics of voltage and current waveforms | Detecting harmonic-related deterioration and waveform distortion trends |
| Power Frequency Voltage and Active Power | Power frequency voltage, active power and phase difference | Evaluating arrester operating status under normal power frequency conditions |
| Energized / Non-energized Testing | Live-line measurement via electric field induction or wireless transmission, replacing PT secondary connection | Routine live-line inspection and outage maintenance testing of arresters |
Regular testing of zinc oxide surge arresters enables maintenance engineers to detect insulation dampness and valve element aging before they develop into failures, helping to plan maintenance work scientifically and extend the service life of arresters and protected equipment.
