What Is The Purpose Of AuxiliaryTransformer In Substation?
An auxiliary transformer is a type of transformer used to power the auxiliary equipment of a substation, such as B. Lighting, heating, ventilation, air conditioning, battery charging, switchgear operation, switchgear drives as well as control and protection systems.
auxiliary transformers are typically step-down transformers that step down the main power source voltage to a level suitable for auxiliary loads.
auxiliary transformers can have various primary power sources, such as the tertiary winding of a power transformer, a distribution feeder, or a dedicated generator.
auxiliary transformers can also provide isolation and fault protection of auxiliary circuits. Auxiliary transformers are essential for the reliable and safe operation of substations.
