DYNAMIC ELECTRIC POWER LINE MONITORING SYSTEM
First Claim
1. A device for attaching to an electrical power line, the device comprising:
- a distance sensor configured to measure the distance of an object to the device;
a wireless transmitter;
a processor adapted to;
interpret the measured distance from the distance sensor; and
transmit a message related to the interpreted distance through the transmitter; and
a power supply configured to supply power to the distance sensor, the transmitter, and the processor.

Abstract
A device and method of precise distance measurement of a transmission line to any object below it is disclosed, along with a network of such devices. The technique employs ultrasonic sensor technology to measure the distance to the nearest object, be it vegetation or a crossing conductor below, and reports that distance wirelessly to the system operator or transmission asset owner. The ultrasonic measurement package may be part of a Transmission Line Security Monitor, which mounts to a transmission line conductor and is powered by the transmission line, transmitting the data by radio links. The technology is equally applicable to encroachment of objects from the side (for example, other transmission lines), as well as to other electrical lines, such as distribution lines, or to other sensing. A built-in transceiver allows the device to communicate with other devices and forward alerts from these devices in a daisy-chain fashion to the intended recipient.
