  Overhead Power Line Monitoring
This project involved a system that was developed to remotely monitor overhead distribution lines in cities and towns locally and abroad. Used on 4,000 to 45,000 volt lines. Key features are the transmission of data via a 88 MHz to 108 MHz RF carrier a short distance to a receiver and PC board that gathers and stores this information. The data is then forwarded through a modem and cellular phone to an office somewhere in the country. Not only is the data able to be received but also all programs and controls on data storage could be remotely changed by this remote link. All information and controls can also be changed locally as well by a handheld device. The transmitter on the power line used a microprocessor and ADC IC to measure amps, volts, pf, etc. The receiver contained a microprocessor to convert received data and convert this signal into an analog signal using a DAC IC. Measured signals could also be displayed on a hand held LCD unit. Watchdog circuitry was also developed to keep the microprocessors running and operating correctly.
