Abstract
A system for detecting the contact of vegetation or other objects with a power line conductor and that may provide an automated notification thereof is provided. In one embodiment, the system may assess one or more power line communication links to determine baseline performance parameters thereof and set associated communication thresholds. The system may also include sensors for measuring wind speed, power line voltages, and/or other data. In one embodiment, the measured data may continuously be time stamped and stored in memory. Sensed data such as voltage and/or wind speed is analyzed during the time of a degradation of a communication link. If there is a correlation in the occurrence of increased wind speed or decrease in voltage and one or more degradations of a communication channel, a notification may be transmitted. In addition, the system may determine location information of the contacting vegetation by determining that surrounding communication links were not degraded during the same time interval.
