You may never have seen a distribution transformer before but they exist in most commercial, industrial, and government buildings. Transformers are used to decrease the energy used by utilities for power distribution to lower levels. They supply energy to individual circuits. These are great at saving energy. It is estimated a savings of 60% power from modern transformers over old ones. Moreover, the lifetime of these equipment is estimated at 32 years. However, they should be replaced before reaching the estimated time because the damages of an unplanned shutdown can be extensive. Our Honolulu electric contractors can give you an estimate of how much energy you can save by having a commercial transformer in your building in Hawaii.
