Abstract

An electrical measuring apparatus comprising a current domain magnetometer (C.D.M.) 1 and summation means 2 for summing the output pulses from the C.D.M., the sum of the summation means representing the integral of a predetermined function of the voltage and magnetic flux applied to the C.D.M. with respect to time. The predetermined function may be proportional to the product of the voltage and magnetic flux and the apparatus may produce measurements of voltage, magnetic flux, power or phase angle. <IMAGE>
