What is the function of a High Voltage bus tie breaker?
Direct Answer
Option B: Connects or isolates two separate HV busbar sections for operational flexibility and redundancy
A bus tie breaker provides operational flexibility by allowing the interconnection or isolation of separate HV busbar sections. This redundancy is vital for load sharing between generators and maintaining power supply to essential services during maintenance or fault conditions, as outlined in standard marine electrical distribution design principles for high-voltage systems.
