Overhead power line monitor

摘要

A device for monitoring and measuring the electrical and mechanical parameters of a power line conductor. Sensors of the device measure conductor temperature, the angle of inclination of the overhead conductor, current flowing in the conductor, and voltage to ground. The device has a low-power mode in which parameters of the power line conductor are not measured. Upon detecting a change in an electrical or mechanical value of the power line conductor, the device measures parameters of the power line conductor for a predetermined length of time before returning to the low power mode.

主权项

1. An apparatus for monitoring the operation of an electric power line conductor having a plurality of catenary segments, comprising:
one or more sensors to measure respective parameters associated with the power line conductor in a particular catenary segment; a level sensor to detect a continuous vibration of the power line conductor in excess of a predetermined threshold level and less than a predetermined frequency for a predetermined length of time in the particular catenary segment and in response cause the apparatus to switch from a quiescent operating mode to an active operating mode; and
a power source independent of the power line conductor,wherein the one or more sensors measure respective parameters associated with the power line conductor in the particular catenary segment for a predetermined length of time when the apparatus is in the active operating mode, andwherein the one or more sensors do not measure the respective parameter when the apparatus is in the quiescent operating mode, wherein the apparatus further comprises a controller for generating status information of the apparatus, and the status information is transmitted to another monitoring apparatus in ‘daisy chain’ fashion at predetermined intervals.
