The existing 15 kV Allis-Chalmers FC Switchgear contains the original vintage air magnetic circuit breakers and electro-mechanical relay protection and was manufactured and installed in 1970. Additionally, the breakers rack into the switchgear using a floor ratchet system and is obsolete when compared to current remote racking technology. The electrical switchgear is old, sheltered isle, outdoor switchgear located within an electric room shell building. The switchgear enclosure, instrument transformers, bussing, and cables are in good working order and have regular maintenance performed. Contractor shall modernize the circuit breaker technology from Air Magnetic to Vacuum and replace the ratchet racking system with a remote racking device with 25 pendant to a controller. Additionally, all (5) switchgear doors will be replaced with new solid state SEL-751 Relays, Relay Test Switches, Electro-Switch breaker control switches, Red/Green push-to test LED pilot lights. On the main and tie breakers, Contractor shall provide kirk key interlock for manual transfer. The above solution replaces the outdated circuit breakers and relays while reusing and not disturbing the existing switchgear enclosure, bussing, instrument transformers, and cables. The Parish of Jefferson expects an additional 30-35 years of service life from the switchgear with recommended maintenance and the elimination of end-of-life components and ratchet racking system
