Abstract

Methods and systems of field upgradeable transformers are provided. Voltage transformation, intelligence, communications, and control are integrated in a flexible and cost effective manner. A field upgradeable transformer may comprise a transformer module and a cold plate. The transformer module provides voltage transformation. The transformer module is enclosed in a housing containing coolant with dielectric properties, such as mineral oil. The cold plate may be mounted to the housing and thermally coupled to the coolant. Interfaces to the primary side and/or secondary side of transformer module may be configured to be disposed on the surface of the housing. A field upgradable transformer may comprise various electronic modules that are configured to be mounted to the cold plate. An electronic module may be thermally coupled to the coolant, and may be configured to be coupled to the transformer module. An electronic module may monitor the voltage level of the primary side and/or the secondary side of the field upgradeable transformer, the current level through the field upgradeable transformer, the power factor, and/or the coolant temperature; create an outage alert; communicate with a control center; provide electromechanical tap changing; regulate line voltages, power factor, and/or harmonics; and/or mitigate voltage sags.
