Abstract

The present invention relates to current measurement apparatus. The current measurement apparatuscomprises a measurement arrangementwhich is configured to be disposed in relation to a loadwhich draws a current signal, the measurement arrangement being operative when so disposed to measure the load drawn current signal. The current measurement apparatusalso comprises a signal sourcewhich is operative to apply a reference input signal to the measurement arrangementwhereby an output signal from the measurement arrangement comprises a load output signal corresponding to the load drawn current signal and a reference output signal corresponding to the reference input signal. The current measurement apparatusfurther comprises processing apparatuswhich is operative to receive the output signal and to make a determination in dependence on the reference output signal and the load output signal, the determination being in respect of at least one of the load drawn current signal and electrical power consumed by the load.
