This specification describes the functional and performance requirements for single shot three-phase Delayed Automatic Reclosure (DAR) for busbar connected feeder circuits and transformer LV circuit breakers, when the transformer's HV connection is banked/connected to a mesh/busbar corner. Figure 1 illustrates typical applications. National Grid's system operates at 400, 275 and 132 kV.
Informative: The requirements for DAR at Mesh/Single switch stations are covered by NGTS 3.24.63.
