Handling 10kV busbar power failure
Circuit Breaker Failure to Operate or Maloperation: Check the energy storage mechanism, closing/tripping coils, auxiliary switches, and secondary circuits. IV EXECUTIVE. The high magnitude fault currents require high-speed operation of the busbar protection to limit equipment damage. However, this high-speed clearing must be balanced against the need for security. Tripping incorrectly for an external fault may cause large outages, and jeopardize power system. Even if distance protection is used for all utility feeders, the busbar will be located in the second protection zone of all the distance protections, so a bus short circuit will be slowly cleared, and the resultant voltage dip may not be permissible. Remote end-line protections served as the main.
