Abstract
A portable auxiliary cooling system for cooling electrical power transformers is provided with an intelligent controller that is programmable for functioning in a plurality of different operational modes. A plurality of sensors monitor cooling system equipment operation, transformer top oil temperature and transformer current. The cooling system controller includes a user-interface panel, a modem and/or other digital communications circuitry, data storage memory and a computer or microprocessor that performs real-time heat removal rate computations and automatically controls heat pump and fan operation in response to the computed results. System performance data, sensor readings and alarm condition indications are indicated on a user-interface panel and may also be provided to a remote station or operator using conventional digital communication facilities.
