Electrical distribution equipment refers to the various devices and components used to control, protect, and distribute electricity throughout a power system. The distribution system typically starts from the substation, where electricity is stepped down from high voltage to lower voltage for use. Distribution substation is a substation from which electric supply is distributed to the different users. In a substation there are numbers of incoming and outgoing circuits each having its isolator, circuit breaker, transformers etc. These equipment are mostly static. Isolation switches, also known as disconnector switches or isolators, are mechanical switching devices designed to ensure that an electrical circuit can be completely de-energized for safe maintenance, inspection, or repair work.
