Signal Detection: Utilizes high-sensitivity sensors or detection circuits to sense partial discharge signals generated by high-voltage electrical equipment during operation. These signals typically manifest as weak current pulses, electromagnetic radiation, or ultrasonic waves. FEM100 P0973CA features a wide frequency range detection capability, enabling it to capture partial discharge signals across different frequency bands for more comprehensive detection of equipment partial discharge conditions.

Signal Processing: Adopts advanced signal processing algorithms to analyze and process detected signals. These algorithms can remove noise interference, enhance useful signals, and improve detection accuracy and reliability. For example, digital filtering technology can filter out common electromagnetic interference noise in power systems; methods such as wavelet analysis are used for signal feature extraction to better identify characteristic parameters of partial discharge signals, such as discharge amplitude, discharge phase, discharge frequency, etc.

Data Communication: The module has excellent communication capabilities, transmitting processed data to the host computer or control system via fieldbus or other communication interfaces. This allows staff to view the partial discharge status of high-voltage electrical equipment in real time at the remote monitoring center, enabling remote monitoring and diagnosis of equipment. It also supports communication and data sharing with other related devices or systems for more comprehensive analysis and decision-making.

Dual-Channel Design: FEM100 P0973CA adopts a dual-channel design, enabling simultaneous measurement of multiple signals. This means it can simultaneously detect and analyze partial discharge signals from different positions of the same equipment or different types of partial discharge signals, or synchronously monitor partial discharge conditions of multiple equipment, thus providing a more comprehensive grasp of equipment operating status and improving detection efficiency and accuracy.
