How does a non-contact voltage tester work
WebAug 12, 2024 · Non-contact voltage testers work by sensing a very small amount of current that is capacitively coupled from the live circuit to the tester and back to ground. Non-contact voltage testers light up when they detect this current without needing to make direct contact. How do you use a non-contact voltage tester on a light switch? WebNon contact voltage detectors take advantage of capacitive coupling that occurs in AC in order to figure out if there is power or not. Now, what people usually do is simply stick the detector into one side of the socket (the live side). This part completely confuses me, how is it possible to detect if there is power if the circuit is open?
