The TZY-PDM-B transformer partial discharge online monitoring system can monitor the internal partial discharge situation during the operation of the transformer in real time, and can provide timely warnings for abnormal insulation status and discharge faults of the transformer, providing guidance data for the normal operation of the transformer and improving the reliability and effectiveness of the transformer operation. The system adopts a miniaturized and modular structure design, which can monitor and analyze the partial discharge signals inside the transformer in real time, and form effective evaluation and diagnosis results; The system adopts fiber optic Ethernet and mobile wireless network to achieve data interconnection and sharing, and users can real-time grasp the operating status of the monitored transformer anywhere.

1. Multiple methods are used to monitor partial discharge online and capture sudden faults caused by internal transients in transformers from all aspects.

2. Built in transformer insulation defect diagnosis system, providing real-time, fast, and accurate transformer status, quantified with indices, and displayed to customers.

3. Small overall size, light weight, portable and lightweight; The cabinet is equipped with shock absorbers, which reflect the stability and impact resistance of the internal equipment.

The communication adopts mobile wireless network and has Ethernet communication interface, which can achieve seamless connection with the SCADA system of the power system.

The hardware adopts an integrated design, with high integration and stable and reliable performance.
