ST-JFWB Smart PD Monitoring Centralized Host

Overview: When partial discharge occurs, voltage and current pulse signals propagate along the inner surface of the metal enclosure of the test object. When encountering openings, joints, and other gaps, they exit the device and propagate along the outer surface of the metal enclosure to the ground. The instantaneous voltage value varies from a few millivolts to a few volts and exists for a very short time. After the discharge pulses are detected by an external capacitive probe, they undergo a series of amplification, filtering, and other processing before entering the acquisition unit for processing. Finally, the test software analyzes and processes the discharge signal. The ST-JFWB intelligent partial discharge monitoring host (centralized host) is the central processing unit of the partial discharge monitoring system, responsible for centralized processing and analysis of partial discharge data collected from multiple sensors. With powerful data processing capabilities and rich display functions, it can display partial discharge data and alarm information in real time, providing operators with intuitive monitoring interfaces. Suitable for centralized monitoring of partial discharge in multiple switchgear.
