The capacitor bank provides reactive power
at grid substation. The voltage regulation
problem frequently reduces so of circulation
of reactive power.
Unlike the active power, reactive power can
be produced, transmitted and absorbed of
course with in the certain limit, which have
always to be workout. At any point in the
system shunt capacitor are commonly used
in all voltage and in all size.
Capacitors are used to control the level of the voltage supplied to the
customer by reducing or eliminating the voltage drop in the system
caused by inductive reactive loads.
An AC system cannot function with the highest transmission capability at
minimum cost and at the highest efficiency unless the reactive
compensation is carefully applied. The capacitor i.e. VAR is installed in
receiving substation, load substation for fast, staples control of reactive
power compensation of voltage control .
Capacitor banks are installed following purposes:
- To improve the power factor of the system & there by regulating the system voltage
- Reactive power compensation
- To reduce the loss
- Increased voltage level at the load
- Reduced system losses
- Increase power factor of loading current
Benefits of using the capacitor bank are many and the reason is that
capacitor reduces the reactive current flowing in the whole system from
generator to the point of installation.
The insulator for the overhead lines provides insulation to the power .
