Situational awareness system and method for disconnect switches in electrical substations
First Claim
1. A method for providing situational awareness to a lineworker executing a switching order in a distribution substation, the method comprising the steps of:
- wirelessly transmitting a status of at least one circuit breaker in the distribution substation;
wirelessly receiving the status at a location adjacent a target switch in the distribution substation; and
displaying the status to a lineworker at the location to allow the lineworker to verify the status immediately prior to executing a switching order for the target switch;
wherein the wirelessly transmitting step comprises transmitting a status for each of a plurality of circuit breakers in the distribution substation, and the displaying step comprises displaying the status for a specific circuit breaker associated with the target switch; and
wherein the wirelessly receiving step comprises receiving the status for each of a plurality of circuit breakers at a plurality of locations by a plurality of wireless receivers, each location being adjacent one of a plurality of target switches and being associated with one wireless receiver of the plurality of wireless receivers and the displaying step comprises displaying at each location the status for a specific circuit breaker associated with the target switch adjacent the location.
