Overhead power line sensor with motion detection

A sensor comprising:

• a housing comprising:
• a body, and an annulus extending from the body;
• an attachment device on an exterior of the housing, the attachment device configured to hold the housing to a suspended power line;
• an electrical measurement apparatus in the annulus;
• an accelerometer in the body;
• a communications device in the body;
• and
• an electronic control in the body, the electronic control coupled to the electrical measurement apparatus, the accelerometer, and the communications device.

A method comprising:

• accessing electrical data from an electrical measurement apparatus in a housing that is attached to a suspended power line;
• determining whether a fault condition is present on the suspended power line based on information from the electrical measurement apparatus;
• accessing information from an accelerometer in the housing;
• determining whether the suspended power line is in motion based on information from the accelerometer;
• and
• if a fault condition is present on the suspended power line or if the suspended power line is in motion, controlling a communications device to send an alert to a receiver that is outside of the housing.
