Busbar System

≪ Previous Next ≫

Busbar system is a system where all incoming and outgoing feeders, lines, transformers are connected through isolator and breaker. The bus bar is used at all voltage level sub-stations and plants. And different types of bus-bar system are utilized as per requirement.

The selection of any busbar system depends upon the following points:-

  1. Amount of flexibility required in operation.
  2. Immunity from total shut-down.
  3. Initial cost of the installation.
  4. Load handled by the busbar.

The different type of bus bar system is given below:-

  1. Single busbar system.
  2. Single Busbar with sectionalization.
  3. Main and Transfer Bus arrangement.
  4. Double Bus Double Breakers.
  5. Breaker and One-and-one-half system.
  6. Ring mains system.
