12. BUS TIE breaker controller
12.1 BUS TIE breaker controller overview
12.1.1 Description
Each BUS TIE breaker controller controls one bus tie breaker. Before closing the bus tie breaker, the power management system
synchronises the busbar sections.
Before opening the bus tie breaker, the power management system de-loads the bus tie breaker. The power management system
also ensures that enough power is available on each busbar section after the bus tie breaker opens.
12.1.2 Applications
There is no restriction on the number of BUS TIE breaker controllers. There can be a ring busbar connection.
