US 6,798,190 B2 · Compact intelligent electronic device incorporating transformers

Abstract

An intelligent electronic device (IED) is disclosed for managing, measuring and controlling the distribution of electric power. The IED includes an enclosure. The enclosure houses electrical circuitry and a transformer that includes windings. A resin is set within the enclosure. The resin electrically isolates the windings of the transformer from analog circuitry. A central processing unit is housed within the enclosure. The central processing unit is coupled to the analog circuitry and operative to calculate at least one power management function. At least one of a display and a communications interface is housed within the enclosure and coupled to the central processing unit.
