Ground Fault Detection Upgrades at Jetty

Project description

Shore to ship power supply at C-Jetty is ungrounded type, three phase three wire; delta connected and is identical to the power generation on board many modern naval ships. The intent of an ungrounded power configuration is to limit system outage downtime and provide continuity of electrical operation to the load. The shore power supply infrastructure at C-Jetty consists of two substations and fifteen electrical kiosks. This equipment is developing ground fault conflicts due to age, voltage drop issues and incompetent methods for ground detection. Regardless, ungrounded systems are typically unstable in the context of personal safety and fire hazard. Thus, the Canadian Electrical Code means to mitigate these vulnerabilities by implementing a ground fault detection device within the system.
