A Look At The Pros & Cons Of Pole-Mounted Electric Transformers In Residential Areas

When electricity that is flowing through a line has to be converted to the proper level of voltage to be used by most homes and businesses, transformers have to be installed. If you were to drive through any given residential area, it is likely that you would spot at least a few of these pole-mounted devices on the tops of poles. If you are in the process of developing a new neighborhood or residential area, you may be asked by your electrical engineer if you want to go with pole-mounted or ground transformers. Pole-mounted versions have their advantages and drawbacks. Here is a look at the pros and cons to help you decide what will work out best. 

Pro: Pole-mounted transformers reduce the risk of injury to residents. 

When you have transformers set up on the ground, they have to be enclosed in a protected area because it is risky for people who do not understand the risks to have access to the area. Transformers mounted high up on a pole are not going to be bothered by the local residents, and there is far less of a chance that someone would climb up and mess with the transformer and get hurt. 

Con: Pole-mounted transformers can be harder to maintain. 

One of the biggest downfalls to transformers that are mounted on a pole is that when something goes wrong, you have to get specific electrical companies out to do the work that has the know-how to reach the transformer on the pole and do the work on it. On the ground, accessibility is easy, so maintenance is less likely to go disregarded and if there are problems, they can be tended to faster. 

Pro: Pole-mounted transformers are compact and don't take up valuable ground space. 

If you are working with a smaller piece of land in the neighborhood that is under development, it can be illogical to designate a piece of it for housing a transformer station on the ground. With pole-mounted transformers, there is no worry about ground space having to be utilized. 

Con: Pole-mounted transformers may have to be replaced faster. 

Because these transformers are mounted high above the ground, they are highly exposed to the elements. Even though the encasements of these transformers are designed to be highly resilient to things like wind and rain, they do sometimes have to be replaced before a ground transformer would.
