Claim 7:
8. A method comprising:
receiving electrical power from an electrical bus at resistive elements of a grid assembly;
cooling the resistive elements by operating a blower drive while receiving the electrical power at the resistive elements from the electrical bus;
continuing to cool the resistive elements by continuing to operate the blower drive after the electrical power is no longer received by the resistive elements for a period of time, the period of time during which the blower drive continues to operate after the electrical power is no longer received by the resistive elements based on one or more operational parameters of the grid assembly; and
ceasing operation of the blower drive after the electrical power is no longer received by the resistive elements for longer than the period of time.
