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.

At least one sensor may also be provided integrally with the components for detecting faults or for sensing general power line conditions. A preferred voltage sensor has resistive shielding for accurate sensing in adverse environments.

Abstract: A line condition sensing device, e.g. a current transformer and/or a voltage transformer, is embedded in a pole mounted, power line supporting insulator to form an integral unit therewith. One end of the insulator carries a pole mounting base. The other end of the insulator carries a power line receiving clamp. The line condition sensing device is connected in parallel with a hot power line by taps to permit conditions to be monitored without cutting or dead ending the line. The device is installed on a hot line by opening the power line receiving clamp of the original insulator, holding the power line in spaced relationship from the original insulator while replacing it with the new insulator, resecuring the power line on the clamp of the new insulator, and then connecting the taps to the hot power line.
