The entire circuit is run by leeching power from an AC current transformer, wrapped around one of the power lines of an AC appliance.

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

Figure 1 Inductively coupled trigger circuit employs a standard current sense transformer (T1), large burden resistor (R2), input comparator (U1), flip-flop (U2), and output comparator (U3). Pulse ...

Unlike the voltage transformer, a current transformer measures current from one circuit to another, which requires different calculations to create the optimal design.
