Abstract
A systems and methods for monitoring an electrical power distribution grid including a plurality of sensor devices forming a sensor wireless network are disclosed. Each sensor device monitors and measures attributes of line current for an associated electrical power distribution line at a selected location. A sensor device detects a fault on the branch of the power grid, determines if the one of the plurality of sensors is at a tail end, sends a fault detected message to an adjacent upstream sensor, or otherwise sends a sleep command to an adjacent downstream sensor from the tail end sensor to disable transmission.

A method for monitoring an in an electrical power grid, comprising:
- in a branch of the electrical power grid:
- detecting a fault by one of a plurality of sensors on the branch of the power grid;
- determining if the one of the plurality of sensors is upstream from the fault;
- provided the one of the plurality of sensors is at a tail end from the fault,
- sending a fault detected message to an adjacent upstream sensor;
- and
- otherwise,
- sending a sleep command to an adjacent downstream sensor from the one of the plurality of sensors for suppressing data transmission of the adjacent downstream sensor.
A system for monitoring a fault in an electrical power grid, comprising:
- a plurality of sensors on the electrical power grid, each sensor including a processor and a memory having computer readable instructions stored thereon, causing the processor to:
- detect a fault by one of the plurality of sensors on a branch of the power grid;
- determine if the one of the plurality of sensors is upstream from the fault;
- provided the one of the plurality of sensors is at a tail end from the fault,
- send a fault detected message to an adjacent upstream sensor;
- and
- otherwise,
- send a sleep command to an adjacent downstream sensor from the one of the plurality of sensors for suppressing data transmission of the adjacent down-stream sensor.
