body
BACKGROUND
The Orange County Sanitation District (Sanitation District) Plant No. 1 Power Building 5 12 kV circuit breakers are over 20 years old and have reached the end of their useful life. The Toshiba VK type 1 circuit breakers currently in service are obsolete and no longer supported nor repairable by Toshiba’s field service repair shop. Replacement parts are also not available. Toshiba redesigned the circuit breakers and changed their designation to HVK. The Toshiba HVK circuit breakers are the only circuit breakers compatible with 12 kV switchgear in Power Building 5.
RELEVANT STANDARDS
• Protect Orange County Sanitation District assets
• Maintain a proactive asset management program
• Sustain 1, 5, 20-year planning horizons
• 24/7/365 treatment plant reliability
PROBLEM
Toshiba model VK circuit breakers have reached the end of their useful life. Preventive maintenance performed identified contact wear at their maximum allowable limit. Toshiba no longer supports repair services because parts are unavailable for these circuit breakers.
PROPOSED SOLUTION
Competitively bid and subsequently approve a purchase order to the lowest responsive and responsible bidder, for the purchase of eight new Toshiba HVK 12 kV circuit breakers for Plant No. 1 Power Building 5.
TIMING CONCERNS
The replacement of 12 kV circuit breakers are required for reliably switching power to the Plant No. 1 Digester Facilities. A delay in procurement may impact the ability to switch power from multiple sources due to risk of a circuit breaker failure which impacts reliability for processing solids.
RAMIFICATIONS OF NOT TAKING ACTION
Failure to act increases the risk of circuit breaker failure resulting in a disruption of power distribution throughout Plant No. 1, impacting process and our ability to treat wastewater.
