Six common bus configurations in substations up to 345 kV
Higher reliability than single bus scheme. Isolation of bus sections for maintenance. Loss of only part of the substation for a breaker failure or a bus fault. 2.2 Disadvantages. A sectionalized bus arrangement has a higher cost than a single bus scheme. Additional circuit breakers are required for sectionalizing.
