Development and evaluation of environmentally sustainable technologies for animal exclusion at transmission stations

At Ontario Hydro the high cost of animal-caused outages has been a concern for a long time. The objectives of this study are: to evaluate the effectiveness of existing animal exclusion methods currently being used at Ontario Hydro and elsewhere; and to develop and assess any new technologies. The criteria for evaluating various animal control technologies include effectiveness, cost, sustainability, maintenance requirements and operational requirements. The information presented here focuses on the development and evaluation of an acoustical system, a nonelectric fence and an electric fence.
