Compact intelligent electronic device incorporating transformers
First Claim
1. An intelligent electronic device, the device comprising:
- an enclosure;
connectors inset into said enclosure;
a first transformer set within the enclosure and coupled to at least one of said connectors, the first transformer including at least one winding;
analog circuitry within the enclosure and coupled to the first transformer;
a resin set within the enclosure, wherein the resin electrically insulates the at least one winding of the first transformer from at least one of the analog circuitry and the at least one connector;
a central processing unit coupled to the analog circuitry and operative to provide at least one power management function; and
at least one of a display and a communications interface coupled to the central processing unit and operative to provide access to said power management function.

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.
