OM.R925 Switchgear Partial Discharge Online Monitoring System

Product Overview 
The OM.R925 switchgear Partial Discharge Online Monitoring System is specifically designed for monitoring the insulation condition of switchgear equipment. It utilizes (Ultra-High Frequency, High-Frequency, Transient Earth Voltage, and Ultrasonic) sensors to continuously detect partial discharge signals inside the switchgear in real time. The system then analyzes and processes these signals in the background, enabling an assessment of the switchgear's insulation status, identification of defect types, and pinpointing the approximate location of any faults. Finally, it provides actionable maintenance recommendations to prevent insulation failures, minimize downtime, and reduce both maintenance costs and operational disruptions.

System Architecture 
Perception Layer: Real-time monitoring of switchgear can be achieved using ultra-high frequency, high frequency, ultrasonic, and transient ground wave technologies, with signals transmitted to the data acquisition unit either via dedicated cables or through a 470MHz wireless connection. 
Collection Layer: Uses fiber optic or 470MHz wireless communication to connect with the partial discharge diagnosis server. 
Diagnostic Layer: Employs large-capacity real-time database technology to store partial discharge data, and leverages an intelligent neural network algorithm—built upon a partial discharge fault database—to accurately identify fault types. Additionally, it enables early warning of partial discharge faults through event trend-based statistical analysis.

Advantageous Features 
● Utilizing non-invasive sensors to avoid power outages during installation and minimize disruptions to equipment operation. 
● Utilizing ultra-low-power components, the operation and maintenance cycle can reach 5 years when data is uploaded once every 2 hours. 
● 0.83 V/m high-sensitivity sensor—outperforming同类 products with its 1.2 V/m partial discharge sensor—features a "Sentinel Mode" that intelligently detects partial discharge signals to automatically activate and switch to real-time monitoring mode. 
● The integrated on-site service displays the host machine, presenting two- and three-dimensional data charts and other information directly at the location, making operations and maintenance more convenient. 
● By implementing a closed-loop management system of "intelligent monitoring - intelligent diagnosis - predictive maintenance," the reliability and operational efficiency of power equipment are significantly enhanced.
