Closed Bus Tie Breaker – DP2 & DP3

Enhanced safety & propulsion reliability

The PFC system detects possible common source power faults which can lead to loss of all electric power and/or loss of all thrusters when the bus tie breaker is closed.
PFC is a fast acting, monitoring and protection system, using advanced and multi-variable protection functions which are able to detect and isolate faults with a high degree of reliability and precision.
 
The PFC does not replace the traditional electric protection devices, but is an overlaying and complementary system to this. In principal, it will not alter the existing protection, even though it may be found necessary to change some of the protection settings in order to obtain the intended results.
