The San Mateo-Hayward Bridge is one of four critical bridges in the San Francisco Bay Area.  It was built in 1929, and was the longest bridge in the world at the time.  It links the San Francisco peninsula with the East Bay, boasting a 7-mile length with a 2-mile elevated section, which is about 200 feet above sea level.  The electrical system was designed with one 15kV circuit from the San Mateo end and one 15kV circuit from the Hayward end.  The 15kV power distribution system consists of a number of 15kV substations fed by the two circuits.  Two are located beneath the elevated span of the bridge without access from the top of the bridge, and thus presents a big challenge for the removal of the existing switchgear and the installation of the replacement switchgear.  The replacement switchgear is 15kV rated, vacuum draw-out breaker, supervised and controlled by a fiber optic-link SCADA system with automatic controls.  Protective relaying is provided by modern multi-function, programmable digital relays also with fiber optic links.  This IEEE PES meeting presentation discusses challenges and difficulties experienced in the project with lessons learned.
