Description / Abstract:
This guide documents methods and designs to mitigate
interruptions, equipment damage, and personnel safety issues
resulting from animal intrusions into electric power supply
substations, thereby improving reliability and safety, and
minimizing the associated revenue loss.
Purpose
Intrusion by animals into electric power supply substations has
been a problem experienced by most of the electric utility
industry. The costs associated with outages caused by animals
continue to escalate. Although animal problems differ in nature
geographically, the damage to equipment, interruption of or loss of
service to customers, and safety problems encountered by operating
personnel result in the same general concerns.
This guide identifies various animals, the problems they cause,
and mitigation methods. Further, it recommends criteria for
applying mitigation methods, documents survey-reported
effectiveness of various methods and recommends factors for
evaluating effectiveness of methods once they are applied.
