FAQ

1)What are the operating environment requirements for the MOEORW-WPD-V2 Multi-Channel Digital Partial Discharge Comprehensive Analyzer?

Answer: Operating temperature must be between -10°C and 50°C, with storage temperature ranging from -40°C to 60°C. Relative humidity must be maintained between 5% and 95% without condensation. Power supply requires 176–264 VAC, 50/60Hz AC voltage, with a 250V T 5A power fuse installed.

2)What are the key safety precautions for the MOEORW-WPD-V2 Multi-Channel Digital Partial Discharge Comprehensive Analyzer?

Answer: The instrument must be reliably grounded by connecting to a grounded power outlet using an aluminum braided grounding cable. Power connection must be within the specified voltage range to avoid over-range input. Synchronization voltage input must be AC and not exceed the maximum input range. The measurement impedance ground terminal must be connected to the high-voltage system ground terminal with low impedance. When external synchronization is not required, the output terminals must be short-circuited. After field calibration, remove the calibration pulse generator before applying voltage.

3)What precautions should be taken when cleaning the MOEORW-WPD-V2 Multi-Channel Digital Partial Discharge Analyzer?

Answer: Before cleaning, disconnect the power supply and remove the power cord, signal cables, and grounding wire. Only use a damp, soft cloth to clean the exterior casing; solvents or abrasive cleaners are prohibited. Avoid allowing water or cleaning agents to penetrate interfaces, fans, or air inlets during wiping
