Abstract:

This design project developed a system that would monitor primary distribution lines and create a real-time update on any possible obstruction that can cause a line to ground fault using a computer-based application. Data were obtained through a series of tests, prototyping, and simulations, and interviews from company representatives. A number of tests regarding time delay and accuracy were conducted in order to evaluate the system while the interviews helped in comparing the proposed monitoring system with the current system of monitoring distribution lines. The study verified that monitoring primary distribution lines can be done real-time and automatically using sensors, controllers, and a graphical user interface. Each sensor yielded different results, thus creating advantages and disadvantages with the different parameters. Ultrasonic sensors offered much accuracy in a given range while IR beam sensors offered a wider range and a vertical spread of beams for detection. The data propagation using power line communication, through adapters, allowed fewer wires and costs for retrofitting new wires for connection. This also proves that it can be an alternative and effective way of transmitting data. The proponents recommended that the monitoring of distribution lines be automated in areas often needing tree pruning. This can lessen the time and resources used in monitoring trees near primary distribution lines.
