Product Introduction
The MOEORW-WPO51 is a compact, integrated partial discharge test system specially developed for on site diagnosis of 6kV–35kV medium and low voltage power cables. Based on the damped AC oscillation wave (OWTS) principle, the device generates 20Hz–850Hz oscillating voltage to stimulate insulation defects and capture weak partial discharge signals.
The system consists of a lightweight high voltage unit and a portable control terminal, supporting both wired and wireless communication. With the OWTS V2.2 intelligent software, it realizes one stop operation including ranging, calibration, pressurization, data analysis and automatic report generation. It provides safe, non destructive and high precision detection for cable handover tests, preventive tests and fault location.
