UHF partial discharge sensor
UHF partial discharge sensor
UHF partial discharge sensor is composed of communication module, main processor and sensor. The communication module is responsible for data communication with the aggregation node, and the main processor controls the sending and receiving of data through the serial port protocol. The sensor is responsible for collecting PD data, and the main processor processes, analyzes and sends the collected data.
