Low Cost Sensors for Real Time Monitoring of Overhead Transmission Lines

Historically, the cost of systems that operate in real time and extract performance data from overhead transmission and distribution lines has been too high to justify widespread adaption into transmission control systems. This project will develop a low cost, wireless sensor for the real time monitoring of overhead transmission lines. The sensor, developed and demonstrated in Phase I, provided real-time wireless data with more than 99% availability. Analytical results derived from the sensor measurements were verified using high-accuracy field-monitoring equipment. Phase II will involve: (1) adding signal processing/waveform analysis capabilities, including current, voltage, and voltage phasors; (2) engineering the product for manufacturing; (4) carrying out additional field tests; and (5) manufacturing a first lot of devices. Commercial Applications and other Benefits as described by the awardee: The device should have multifunction capability with a very low cost per function. Commercial applications include dynamic line rating, clearance monitoring systems,
