Barnch out the main supply.
Can segregate between critical & non-critical load.
TYPE
DOUBLE BUSBAR
DOUBLE BREAKER
DISADVANTAGES
Cost of the system & maintenance is more.
ADVANTAGES
Used on higher voltage levels.
More operating flexibility.
Requires more breakers.
SINGLE BREAKER
DISADVANTAGES
Cost increase.
May breakdown if any fault occurs in any of the section.
ADVANTAGES
Maintenance without circuit removal.
Easy to shift the load.
Less maintenance cost.
Operated by using the bus potential.
SINGLE BUSBAR
WITH BUS COUPLER
ADVANTAGES
Helps to reduce faults.
Easy to remove the fault section.
Can be repaired without disturbing the overall section on the busbar.
DISADVANTAGES
Increases the cost.
WITHOUT BUS COUPLER
