Product Introduction

MOEORW-WPD530NC is an integrated, portable partial discharge detector for live detection of power equipment. It adopts ultrasonic, transient earth voltage (TEV), ultra-high frequency (UHF) and high frequency (HF) technologies, and runs on Linux system with a 6.2-inch touch screen. It can quickly capture partial discharge signals, display PRPD/PRPS and other spectrum diagrams, realize quantitative analysis and defect location, and is widely used in daily inspection and status evaluation of high-voltage cables, transformers, switch cabinets, GIS and other equipment.

FAQ

Q1:How to turn on and off the instrument?

A:Press the power button at the bottom to turn on; press again to turn off. Please charge when the low battery icon appears.

Q2:Can it be charged while working?

A:No. Charging must be done when the instrument is turned off, and the original charger should be used.

Q3:How to export test data?

A:Insert a FAT32 U disk into the top Type-C port, select data in the "Stored Data" interface, and click "Save to U disk".

Q4:What should I do if the signal is disturbed?

A:Test the background noise first, set appropriate threshold and filter, and keep away from strong interference sources.

Q5:Can it be used in thunderstorm weather?

A:No. Measurement is prohibited in thunderstorm, explosive and other dangerous environments.

Q6:How to maintain the instrument?

A:Store in dry and ventilated place; avoid direct sunlight; turn on for about 2 hours every month in humid season to dehumidify.
