Substation Components - Miracle Electronics
For all operations related to power systems the
main constituents of power generation,
transmission, and distribution systems
substations are required for completing the
required actions. Substations are groups of
electrical equipment through which customers get
supply of electrical power from generating
stations. The electrical quantity in substations
can be altered by varying the voltage and
frequency levels to provide quality power to
consumers. Substations are classified into
various types depending upon their applications,
namely indoor substation, outdoor substation,
generation substation, converter substation,
distribution substation, switching substation,
transmission substation, pole-mounted substation,
and collector substation. A substation is a
combination of various electrical equipment, with
the most important ones being transformers,
conductors, insulators, isolators, circuit
breakers, relays, lightning arresters, bus bars,
and capacitor banks.
Transformers Transformers are electrical machines
used for transforming power from one circuit to
another without changing the frequency. These
transformers are used to step up or down the
voltage levels of a system for transmission and
generation purposes. There are multiple varieties
of transformers based on their design, purpose,
utilization, and installation. You can get the
best kinds of toroidal, medical isolation,
three-phase, EI, audio line matching, SMPS, UI,
and power transformers in India at Miracle
Electronics, one of the most reputed names in the
country for such electronic equipment.

Conductors Conductors are materials that are made
of metals that comply with electrical property
conductance, and allow the flow of electric
charge by permitting free movement of electrons
to flow through them. This helps in power
transmission or electric energy transfer from
generating station to consumer point, where power
is consumed by the loads. The most commonly used
conductors used in power systems are those made
of aluminum. Insulators Insulators, unlike
conductors, do not allow free movement of
electrons or electric charge through them. This
is why insulators resist electricity with their
high resistance, and are used for insulation
while erecting electric poles with conductors to
avoid short circuits. The various types of
insulators include suspension, stray, pin,
strain, and shackle insulators. Isolators Isolato
rs are manually operated mechanical switches that
isolate the faulty sections or those sections of
conductors or circuits that need to be repaired,
in order to avoid occurrence of harsher faults.
The various types of isolators used in different
applications include single-break, double-break,
line, and bus isolators. Circuit Breakers Due to
short circuits or any other faults, the faulty
sections are disconnected automatically by
circuit breakers to protect the substation and
its components from over currents or over load.
After the fault is rectified, the original
circuit is then rebuilt. Different types of
circuit breakers are designed based on different
criteria and usage, with the most commonly used
ones being oil, air, vacuum, and SF6 circuit
breakers. Relays Relays are used for
disconnecting circuits manually or automatically.
They consist of excited or energized coils
connected in such a way that the contacts of
relay when closed activate the relay to break or
make the circuit connection. There are multiple
types of relays like voltage, auxiliary, over
current, directional, reclosing, and
microcontroller relays. Lightening arresters In
cases of light surges, a high voltage passes
through all the electrical components of a
substation, causing them damage. To avoid this
issue, lightning arresters are placed to pass the
lightening surges to the earth.

Bus bars Bus bars are current carrying conductors
that have multiple numbers of incoming and
outgoing line connections. These are classified
into single bus, double bus, and ring bus
bars. Capacitor banks Capacitor banks are sets
of identical capacitors connected in series or
parallel within an enclosure, used for power
factor correction and protection of substations.
These banks are sources of reactive power, and
can reduce the phase difference between voltage
and current. They are the best equipment for
maintaining power factor and correcting power lag
problems. For More details visit Miracle
