A guide to transformer protection for engineers of electrical engineering An overview of transformer protection for engineers of Electrical Engineering primarily focuses on the application of protective relays for the protection of power transformers. It includes an emphasis on the most prevalent protection schemes and transformers. It refers to a specific instruction manual for your relay. The references provide a source for additional guidance of theory and application. The engineers of B Tech Colleges in Jaipur must balance the expense of applying a particular protection scheme against the consequences of relying on another protection transformer.
