Unitized substations may be indoor or outdoor, with a selection of high - voltage incoming sections, a choice of transformers types and an arrangement of switchgear to suit the application.Most switchgear to suit the application.Most switchgear assemblies are configured as unit substations.Unitized substation follow the system concept of locating transformers as close as practicable to areas of load contentration at utilization voltages, thus minimizing the lengths of secondary distribution cables and buses. Lengths of cables and buses are minimized,reducing the likelihood of faults and improving voltage regulation.
