What Will I Learn?
This course takes you from core transformer theory through every aspect of autotransformer design, analysis, and application. You will learn to solve voltage, current, and efficiency problems using equivalent circuit models and the per-unit system. Three-phase configurations, including wye, delta, Scott-T, and open-delta connections, are covered in full detail. You will also study protection systems, grounding practices, and fault diagnosis techniques used in real installations. Motor starting, transmission interconnection, and renewable energy integration round out the practical application topics. Testing, commissioning, and preventive maintenance procedures prepare you to work confidently on autotransformers in the field.
