Product Name: HC8011 Transformer Partial Discharge Online Monitoring System
Category: Substation Intelligent Online Monitoring System
Detailed Introduction
Product Introduction
HC8011 Transformer Partial Discharge Online Monitoring System adopts ultra-high frequency, ultrasonic and pulse current comprehensive monitoring methods, which can determine the instantaneous change of partial discharge of the monitored equipment and the change trend of discharge amplitude in real time. The system has a complete network alarm function. Not only can multiple systems be interconnected through the network and share a background, it also supports remote background management and local background remote management. It can also realize remote data transmission and remote control of equipment through telephone network, mobile network and Internet network, and conduct remote online monitoring, status operation analysis and diagnosis.
Functional features
※ Adopts comprehensive detection methods of ultra-high frequency signals, ultrasonic signals, and pulse current signals;
※ Able to determine the current amplitude of partial discharge of the monitored equipment and the change trend of discharge amplitude in real time;
※ The system has the functions of partial discharge trend analysis and real-time alarm of partial discharge value;
※ Able to integrate multiple anti-interference technologies to realize online monitoring of partial discharge under strong interference environment;
※ Able to display transformer partial discharge waveform and data in real time and observe the current partial discharge of the transformer;
※ The system can adopt multi-channel data acquisition and can comprehensively process various types of signals such as discharge pulse current signals, ultrasonic signals, ultra-high frequency signals, etc.;
※ The system has a complete network alarm function. Multiple systems can not only be interconnected through the network and share a background, support remote background management, but also support remote management of local background;
※ Historical trend graphics, historical record data, alarm records and real-time waveforms can be checked at any time on the background computer. This function can receive data “at any time and any place”.
