High Voltage Busbar Protection
Even though the likelihood of a short circuit is greater, the risk of widespread damage is lower. In principle, busbar protection is needed when the system protection does not protect the busbars, or

Home / Function of 35kV busbar PT winding
Potential or Voltage Transformer: The purpose of the Potential Transformer is to provide an isolated secondary voltage that is in-phase and exact proportionate representation of primary voltage. Common methods of protecting busbars include overcurrent-based interlocking schemes, overcurrent-based differential protection, high-impedance differential protection, and percentage differential protection. Busbar protection (BBP): Protection intended to detect and operate to clear faults on a busbar. The PT cabinet, also known as the busbar voltage transformer cabinet or voltage transformer cabinet, typically houses a set of voltage transformers, a circuit breaker, surge arresters, and other primary electrical components.
