Substation
Before electricity can be
delivered to customers, it must travel through a distribution substation.
Distribution substations, located near where electricity will be used,
monitor and adjust circuits within the system.
Substations are fenced-in
yards containing switches, transformers and other electrical equipment. The main
purpose of distribution substations is to lower transmission voltage to 24,900
volts or less to feed the distribution system.
Relays are
mechanical switches that will cause a substation breaker to shut off power if it
senses a higher than normal current. Within the substation, rigid tubular or
rectangular bars, called busbars, or buses, are used as conductors to
feed power to two or more circuits. Circuit breakers automatically disconnect
power to a circuit in the event of a failure or interruption in an electric line
(see diagram #4).
