ABSTRACT:
A circuit is provided for obtaining an accurate replica of an active electrical parameter, i.e. a voltage or a current. The circuit is an improvement over prior circuits in respect of accuracy, both in relation to magnitude and phase. When providing a voltage replica, the principal utility is to provide a scaled-down replica of a high voltage that can be used for accurate measurements of power. In its applicability to current, the principal utiity is to provide an accurate scaled-up current reference source, preferably in quadrature to the input voltage, for use in calibration of reactive volt-ampere or volt-ampere-hour meters. The objective of improved accuracy is achieved by combining known scaling-up and scaling down circuits with a current comparator.
