Cleaning of Livefront Electrical Switchgear Using Carbon Dioxide Pellets at Navy Installations
Abstract:
The Objective of this project is to evaluate a promising technique that uses carbon dioxide CO2 pellet media blasting to clean energized power distribution equipment. This process has been in use in industry for some time to clean various kinds of equipment, but its use in high voltage applications has had limited evaluation. The objective is to demonstrate the process on energized approx. 15kV Load Interrupter L.I. electrical switches located on the base at Naval Station San Diego. Demonstration testing is required to enable Navy-wide implementation of the process. Objectives of the test program are verification of cleaning effectiveness, development of safe work practices, and evaluation of potential impacts on electrical switchgear. The project was conducted jointly with PWC San Diego Code 620 and leveraged about 125K of PWC funds to procure a CO2 cleaning system.
