Transformer Protection Types | Nature and Classes of Faults Protection Types: Nature of Transformer Faults: Power transformers, being static, totally enclosed and oil immersed develop faults only rarely but the consequences of even a rare fault may be serious, unless the transformer is quickly disconnected from the system. For the purpose of Transformer Protection Types, faults can be divided into three main classes:
