Abstract
A measurement system includes an arc-fault detection circuit and a second detection circuit coupled to a current transducer. By providing both arc-fault detection and further detection capabilities using the current transducer, the overall circuit size may be reduced. To allow the arc-fault detection circuit and the second detection circuit to provide detection of different events, the circuits may operate at different sampling frequencies.
