System and method for heating an electrical bus in an electrical cabinet for cold startup and condensation/frost control

Abstract:

A method for heating an electrical bus in an electrical cabinet containing at least one current conversion device includes determining a temperature inside of the electrical cabinet. The method also includes determining a temperature outside of the electrical cabinet. Further, the method includes applying heat to the electrical bus via conduction when the temperature outside of the electrical cabinet is below a predetermined temperature threshold or a difference between the temperature inside of the electrical cabinet and the temperature outside of the electrical cabinet is less than a desired temperature difference.
