ST-JFA3 3-in-1 PD Sensor (UHF + Ultrasonic + TEV)
Overview: The three-in-one sensor intelligent data acquisition unit is designed for high, medium and low-voltage power switchgear. This device must be used in conjunction with the switchgear partial discharge monitoring intelligent sensor (three-in-one). It is a multi-functional partial discharge detection product that integrates online UHF, TEV/ultrasonic/UHF, data acquisition, and data analysis in one. The device provides communication interfaces that can be connected to computer monitoring systems, supports RS485 interface MODBUS-RTU communication protocol, with the characteristics of high detection accuracy, strong anti-interference capability, and convenient networking.
