In almost every place where people live and work you will find at least one transformer. But as long as it keeps working and supplying power to the escalator in the department store, the hotel lift, the office computer, the oven in the local bakery, the farm machinery or the petrochemical plant nobody gives it a second thought. However, transformers are one of the most important units in every production process. Without them the core activities of nearly every business and factory would come to a standstill with serious financial consequences. Distribution Transformers have a long service life if they are operated under rated conditions. The operation of these transformers under conditions such as overloading and voltage unbalance for a long time will reduce their life significantly.
