Unit Substation Transformer

Unit Substation Transformer

Unit Substations may be indoor or outdoor, with a selection of high-voltage incoming sections, a choice of transformer types, and an arrangement of Switchgear to suit the application. Most switchgear assemblies are configured as unit substations. Unit substations follow the system concept of locating transformers as close as practicable to areas of load concentration at utilization voltages, thus minimizing the lengths of secondary distribution cables and buses.
