System Protection, Controls Modifications and Retrofits
Palo Verde Nuclear Generating Station Water Reclamation Facility
In August of 2008 an outage occurred on one of WRF’s two main feeders. Because the legacy equipment required manual operation, an operator in full arc flash suit was required to restore all panels by depressing the manual close button on the front of the breaker. A high risk and time consuming procedure. In the course of restoring power to the lost systems and loads an operator manually closed a tie breaker which resulted in phase to ground arc flash incident.
CPC designed, Implemented, tested, and commissioned a retrofit of the main-tie-main switchboard protection systems for Palo Verde Nuclear Generating Station – Water Reclamation Facility. Project included replacement of electro-mechanical relays, incorporating full automation of transfer sequences, and remote monitoring/control capability.
