Non-invasive AC Current Sensor SCT-013-000.

Non-invasive AC Current Sensors are a good way to measure real consumption without altering the electrical composition of the elements to be analyzed. They work by magnetic induction, so that the field generated in the cable, used to power the device, induces a current in the transformer integrated in the sensor. In this way we can know what the current is in the power cable and therefore the actual consumption of the device to be measured.
