Abstract :
This paper assembles data from various sources in order to provide information to evaluate liquid-filled and dry-type transformers. The first basis of comparison is a general product description of product development and design. The second comparison is a specific comparison of electrical characteristics based on standard and optional ratings. A general description of industry standards with their prevailing focus as well specific references to the applicable industry standards for the products being compared in this review is also provided. The comparison of kilovolt-ampere (kVA) sizes and voltages is based on distribution ratings most commonly used in the United States. Only ANSI and NEMA standards are used as references for the electrical characteristic comparison
