Current sensor is how to detect leakage current?

Leakage current sensor is a type of electromagnetic isolation in accordance with the transformer, magnetic modulation principle of operation will be measured AC micro-current, DC isolation into a linear ratio of DC current, DC voltage and other standard analog signals or RS485 digital signal device. Widely used in DC and AC power supply system bus and branch circuit insulation real-time monitoring. 

Leakage current sensor assembled around the positive and negative outlets in the DC circuit, when the device operates, real-time detection of the branch circuit sensor output data signal, when the branch circuit insulation is all normal, the current flowing through the sensor is equal in size and opposite in direction, and its output data signal is zero; when the branch circuit is grounded, the leakage current sensor has a difference in the current flow through the sensor output is not zero. So by detecting the output data signal of each branch circuit sensor, it can be determined that the DC system is grounded branch circuit. The principle of line selection is highly accurate and is not subject to the interference of line distribution capacitance.

How does the current sensor detect leakage current? See here, I believe we have the answer in mind! Current sensor with its powerful leakage current detection function, in the sensor market to harvest a number of user groups. When we use the current sensor to detect leakage current, we must understand more about the principle of its operation and detection, so that we can use it in a more scientific and efficient!
