Abstract
A circuit for receiving the output from one of either a current transformer or a di/dt sensor includes: an input pair having a first input and a second input; a first output; a second output; a current transformer input circuit connected between the first input and the second input; and a di/dt sensor input circuit connected between the first input and the second input. The current transformer input circuit is configured to receive output from a current transformer connected to the input pair and to output a signal representative of the current sensed thereby via the first output. The di/dt sensor input circuit is configured to receive output from a di/dt sensor connected to the input pair and to output a signal representative of the current or time rate of change of the current sensed thereby via the second output.
