Method And Device For Protection Zone Selection In A Multiple Busbar Arrangement

A computer program product comprising storage means for storing program code which when executed performs a method of protection zone selection in a multiple busbar arrangement, the multiple busbar arrangement comprising busbar zones and bays connectable to the busbar zones, which bays comprise measurement transformers, wherein the method comprises:

• receiving first connection data comprising information of an operational status of measurement transformer to busbar zone connections,
• determining all pairs of connected busbar zone to busbar zone connections based on the first connection data,
• comparing data representing pairs of busbar zone to busbar zone connections,
• based on the comparing, assigning each pair of busbar zones which has a busbar zone in common with at least another pair of busbar zone to busbar zone connection to a respective protection zone, and
• defining any busbar zone that is not connected to any other busbar zone as a protection zone.
