A local electrical system is extremely important, for it helps to ensure all members of a community have access to power throughout the day. While electricity helps to provide us with plenty of comfort in our daily lives, it is also extremely valuable and necessary for medical services and proper emergency response. One of the most important components of any public electrical system is the transformer. A transformer typically sits at the top of a power pole and is typically responsible for stepping the high voltages used for transmission down to the lower voltages used by homes and businesses. Keeping the transformer safe and operational is critical. While most transformers are very reliable, one of the biggest hazards they all face is the risk of being damaged by squirrels and other animals. Fortunately, it is possible to protect an electrical system from critters with our various systems.
