The XHDD405SC wireless series live testing device for ZnO arresters is used for both energized and de-energized tests of arresters of any voltage class. It can effectively discover hidden troubles like internal insulation moisture and valve plate deterioration at an early stage.
It is capable of measuring total current, resistive current and harmonics, fundamental reference voltage and harmonics, active power and phase difference. Real voltage and current waveforms are shown on the large display, with accurate analysis of fundamental and 3rd to 7th harmonic components.
Each measurement function of the XHDD405 corresponds to a specific diagnostic purpose. The table below helps maintenance engineers understand what each parameter reveals about arrester condition:
| Measurement Function | What It Reveals | Diagnosis Value |
|---|---|---|
| Total Current and Resistive Current | The resistive component of the leakage current under working voltage | Detects valve plate deterioration and internal insulation moisture |
| Fundamental Reference Voltage and Harmonics | Reference voltage level and its harmonic content | Evaluates arrester reference voltage drift and aging trend |
| Active Power and Phase Difference | Power consumption and phase relationship of the arrester circuit | Assesses overall operating condition under power frequency voltage |
| 3rd to 7th Harmonic Analysis | Harmonic components of voltage and current waveforms | Identifies waveform distortion caused by harmonic stress |
| Parameter | Specification |
|---|---|
| Full current measurement range | 0 ~ 10mA RMS, ±(5% + 5uA) |
| Resistive current fundamental wave measurement accuracy | ±(5% + 5uA) |
| Current harmonic measurement | ±(10% + 10uA), input resistance ≤2Ω |
| Reference voltage input range | 25V ~ 250V RMS, ±(5% + 0.5V) |
| Voltage harmonic measurement | ±(10% of reading), input resistance ≥1800kΩ |
| Wireless frequency | 433MHz, transmission distance 100 meters |
| Continuous operating time | Over 8 hours; charging time over 6 hours |
| Charging power supply | AC 220V ±10%, 50Hz ±1% |
| Weight | 5kg |
With its built-in battery, calendar clock and micro printer, the XHDD405SC supports up to 120 data records, making it convenient for on-site testing, data archiving and report printing.
