In her article, Transformer Types of Electrical Systems, Anne explains that transformers are an important part of every electrical system; it allows transferring and distributing electricity of different voltage levels. This comparison guide does more than compare different types of transformers, it includes the step-up transformer, the step-down transformer, the isolation transformer, and the distribution transformer. All these types have various functions from increasing voltage level for long range transmission to stepping down the voltage level for end use. Knowing these differences makes it easier for power customers to identify the most suitable transformer to use in their applications in a bid to maintain efficiency and coverage reliability.
