EXECUTIVE SUMMARY

Schneider Electric Services perform Transformer and Switchboard PM in accordance with project specification and applicable industry standard on USS-3 Substation located at VA loading duct tunnel 2002 Holcombe Blvd Houston, Texas 77030. The site contact for this project was Joe

Ceasar of VA Medical Center Electrical Power Distribution Department (713)806-7506.

USS-3 480V Switchboard

USS-3 480V Switchboard Main Breaker trip unit failed to trip during breaker primary injection testing. After troubleshooting was performed, we have found that the trip unit was bad and needed to be replaced. Main Breaker Carriere trip unit was replaced by AC pro trip unit. Time delay curve for the replacement trip unit was set to match the existing trip unit as close as possible since the replacement trip unit and the existing trip unit was not made from the same manufacturer. The trip curve was slightly different from each other. The customer was advised to have a new coordination study to ensure the right protection settings is set to the main Breaker.

USS-3 Spare ME Square D Breaker A-phase and C-Phase contact resistance reading is abnormally higher compare to B-Phase. Loose connection on the breaker will cause a hot spot when energize which can potentially cause a fault that will result to a costly repair to the gear and injury to personnel. It is recommended that the breaker will need to be replaced.

If there are any questions or concerns, please contact:
