Monitor the residual current value, voltage value, load current and temperature value in the protected line, upload the data to the cloud monitoring system in real time through the industrial intelligent power intelligent monitor, and output the monitoring curve through the large screen in real time to ensure the safety of industrial electricity. The I/O output is connected with a smart air switch, which can automatically cut off the power when the alarm occurs, and alert the equipment management personnel through the SMS and WeChat small program to prevent electrical fires from occurring in multiple directions.
