Title: Clamp-on current and voltage module for a power monitoring system

Abstract: A clamp-on current and voltage module for an electrical power monitoring system that monitors characteristics of power distributed through one or more power conductors includes a current transformer having a core divided into at least two parts so that the core can be installed around a power conductor without cutting the conductor. The transformer produces a current signal corresponding to current passing through the power conductor. A pair of clamping elements fit on opposite sides of the conductor, for gripping the conductor. The transformer core parts and the clamping elements have engaging surfaces that prevent relative movement between the CT enclosure and the power conductor in a direction transverse to the axis of the power conductor. A voltage sensor makes electrical contact with the power conductor and produces a voltage signal corresponding to the voltage on the power conductor.
