| Abstract: | Based on the analysis of the detection principle, method and device of partial discharge, an online monitoring device for partial discharge in switchgear cabinet was built by using the method of transient earth voltage (TEV) and acoustic emission (AE), and a comprehensive analysis software with rapid inspection and intensive care functions was developed. The device was tested in practical cases, which verifies high accuracy, sensitivity and excellent anti interference of the comprehensive analysis system of partial discharge in switchgear cabinet based on TEV and AE. The system is portable and flexible, and owns 24-hour intensive care for switchgear cabinets. |
