On line monitoring system of cable partial discharge

1、 Demand analysis

With the progress of science and technology, the proportion of cable lines in cities is also increasing, and the insulation materials in cable lines may have air gaps, harmful impurities, etc. due to materials or processing technology problems, which may cause cable line failures. In order to ensure the long-term operation of the cable line, the cable partial discharge online monitoring system is required to monitor the partial discharge of the cable in real time and give early warning to the fault in the cable line in time, so as to protect the safe operation of the cable.

2、 Working principle

The device has strong anti-interference capability and strong electromagnetic compatibility. It is equipped with antenna gating to continuously interfere with signals and maintain accurate monitoring data. The device can operate independently, record the cable data separately, and use the acquired computer to manage multiple devices through data connection. The device can provide a variety of different alarm modes and has powerful background management software. It has a large amount of data storage and can be moved for backup at any time.
