Transmission Lines in Transmission Systems

Power companies must consider a lot to ensure the successful, consistent operation of an electrical grid, and transmission lines are just one part of that system. Power transmission lines are used for electricity to be transported from generation sources (such as wind or solar farms, coal, or natural gas power plants) to its destination (like your home or business). They must meet technical specifications that obey the laws of physics as well as deal with what nature throws at them, whether it be lightning strikes or critters bent on chewing through that wire. Various strategies can be implemented to minimize such risks to service continuity, but why are components, specifically transmission lines, so important?

What to Do with Substation Fires

Substation fires can be among the most intimidating destructive forces, and there are a number of ways they can get started, depending on the equipment used. The fires are commonly caused by hazards such as a mechanical failure combined with a combustible source, water getting into the system, or even an insulation failure. Many times, squirrels, rodents, raccoons, and other critters are culprits in damage, when they climb into substation plants via unprotected electrical lines and utility poles. These fires are exceptionally dangerous because of their potential for explosions, due in part to leaking oil that causes hazardous smoke. There can also be loose wires that aren't insulated, which could cause shock or electrocution. So, what actions should someone take should they encounter a substation fire?

How Drones Are Helping Power Utility Companies

Keeping squirrels and rodents from damaging your power lines is a top priority for Critter Guard, but these pests are not the only thing to worry about when it comes to keeping the power on. Heavy rainfall, high-speed winds, and debris caused by major weather events can also wreak havoc on a power system. Maintaining the grid calls for regular inspection of potentially damaged equipment to ensure its continued integrity. In recent years, drones have become a safe and cost-effective way of inspecting the grid.

Wildlife Interaction with Electric Utility Components

Human-wildlife interactions are inescapable, even in dense, urban areas. As our populations expand, animals must adapt, which sometimes causes expensive or dangerous damage to property. Power lines and utility components showcase a major conflict; they're crucial for maintaining our modern lifestyle but are attractive to wildlife like squirrels. Rather than turning to traps or poison that are inhumane and dangerous to pets and non-pest wildlife, physical barriers are extremely effective at blocking wildlife access to electrical components. Our Pole Guards and Line Guards act as deterrents and prevent costly damage.

Why Are Power Lines Overhead and Not Underground?

Most people have probably stopped noticing overhead power lines a long time ago; they just feel part of the landscape now. But have you ever wondered why our power lines are up there in the first place? Sure, they're out of the way, but the same would be true if we put them in underground conduits, so why do we still send them skywards?
