body
BACKGROUND
Orange County Sanitation District's (OC San) electrical relays and circuit breakers are protective devices essential in protecting low and medium voltage electrical distribution systems from catastrophic failure during transient, overload or short circuit conditions. ANSI/NFPA 70B recommends that protective relay devices and circuit breakers be verified, tested, and set at intervals of one to three years to confirm accuracy. Testing these devices ensures the reliability and safety of our electrical distribution system and staff working in these areas.
RELEVANT STANDARDS
* 24/7/365 treatment plant reliability
* Comply with environmental permit requirements
* Maintain a proactive asset management program
* Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting
PROBLEM
OC San has circuit breakers and relays that have not been verified within the recommended timeframe. With over 1,250 protective relays and circuit breakers, supplemental support from an InterNational Electrical Testing Association certified contractor helps ensure reliable operation and safety.
PROPOSED SOLUTION
Staff recommends a three-year General Services Contract to Electric Power Systems International, Inc. to provide Protective Relay and Circuit Breaker Testing Services for Treatment Plant Nos. 1, 2, and Pump Stations.
