On-line Monitoring of grounding current of Transformer Core

ECM-701 core grounding current monitoring device is composed of three parts: Sensor, signal transmission cable and monitoring and processing unit. How it works: The core sensor transmits the monitored current to the monitoring unit through the transmission cable in the form of 4-20mA signal, the monitoring unit processes and displays the signal, and transmits it by Modbus protocol. The main features of the device are: 1) the zero-flux Sensor is easy to install, small size, light weight, easy to install, no need to disconnect the transformer grounding copper bar when installing, with the advantages of anti-external electromagnetic, electric field interference, high measurement accuracy, accurate numerical value and so on. 2) measuring the maximum current value is 10A, which can display the real-time current value and the historical large current value, and is convenient for users to grasp the operation status of the transformer. 3) the device can output 4-20mA analog signal directly. 4) remote data transmission through standard Modbus communication protocol.
