Did You Know?
Did you know animal-related outages cost utility companies between $15 and $18 million each year? Snakes, squirrels, rats, raccoons, possums, and birds have turned substations into their jungle gyms and transformers into nests.
Unfortunately, things turn ugly when the animals cause a phase to phase or phase to ground fault with their bodies. Cue the electrical faults, electrocution, and fire. It’s not good for either party involved.
What Can You Do?
The good news is that most people want to protect their electrical assets while protecting these animals. Substations have been trying various solutions to prevent wildlife trespassers, which as you can imagine, has been a nearly impossible task. It is important that the solution isn’t more expensive than the cost itself, and you’ve got to use materials that are both safe for the animals and tough enough to outlast any weather condition.
While you can’t fully protect your electrical assets from rogue animals, you can protect your transformers, cables, circuit breakers, and bushings. You can also prevent electrical failure with Megger’s insulation resistance testing. Learn more on this topic here.
