Underground DTE crews added new cables to a recently installed transformer on Cogswell Road off Van Born in Wayne Township. Underground transformers work differently than transformers on utility poles. Primary cables travel from the utility pole going underground to the transformer, while secondary cables start from the transformer and travel to the building that is being powered. The photo below shows an underground transformer that has a visible split down the center with primary cable functions on the left and secondary is to the right. What does it mean for you? Your power reliability is enhanced because underground equipment is less vulnerable during storms and also protected from outside factors such as animals, cars and trees.
You may see more of our crews in the coming months as part of our accelerated electric reliability projects in your area, including more tree trimming and infrastructure updates. All these projects are underway to improve your service and reliability for the short- and long term.
