Bus Protection Considerations for Various Bus Types
This paper examines several common bus configurations, presents appropriate protection schemes for each configuration, and analyzes the protection scheme complexity, advantages, and disadvantages.
Functional Specification for 15 kV, 25 kV, or 35 kV Underground
The switch mechanism shall use a manually-charged, stored-energy, spring-loaded over-toggle assembly, which is independent of operator speed. The switch shall operate by rotation of the
Functional Specification for 15 kV, 25 kV, or 35 kV Underground
The vacuum switches and their corresponding visible break switches shall be mechanically interlocked such that the visible break switch will never operate under load.
Six common bus configurations in substations up to 345 kV
This technical article explains six most common bus configurations used for distribution, transmission, or switching substations at voltages up to 345 kV. Presented single line diagrams and
