what is purpose of using reactor in substations...

Answer / jnanesh

Reactor is nothing but having a wound coil inside it having
high impedence.Suppose there is an short circuit in
transmission line it limits the short circuit current to
safer value which prevents the connected equipment i.e
breaker or transformer.

what is purpose of using reactor in substations...

Answer / gunasekaran

there r 2 type of reactor
1.parallel reactor using to reduce the ferranti effect.
2,series reactor to limit the fault current.

Is This Answer Correct ?    85 Yes 9 No

what is purpose of using reactor in substations...

Answer / karthi

Due to the ferrantic effect the receiving end voltage is
greater than sending end voltage to avoid this problem we
useing the reactors........

what is purpose of using reactor in substations...

Answer / arvboy

Electrically, reactor has a property that current cannot
change suddenly across its terminals. Initially, when a
reactor is switched on, it acts as a open circuit to
current. (opposite is the case with capacitor which acts as
a short when switched on or sudden current change occurs)
This principal is employed in substation where two buses
are coupled through a series reactor, when a fault occurs
in one bus/its outgoing feeders, it doesn't get transferred
to another section and meanwhile protection acts to isolate
the faulty area.For the same reasons, two separate
switchyards of same voltage levels are connected through a
reactor tie.

Another use of reactors in substation is to be coupled
alongwith capacitor bank to absorb initial current surge
when capacitor banks are switched on.
Further more, due to their lagging current production, they
are also used in conjuntion with capacitors for voltage
control.
Shunt reactors are used in long lines to counter ferranti
effect.

Answer / bl meena

reactor-coil having high inductance compared 2 its
resistance,it's used 2 limit short ckt. currents.

Is This Answer Correct ?    44 Yes 7 No

what is purpose of using reactor in substations...

Answer / rajesh

To reduce short circuit current to lower value

Is This Answer Correct ?    38 Yes 11 No

what is purpose of using reactor in substations...

Answer / minal

in order to balance the capacitance current that is
produces in substations, we are using reactor.
we know that xL =i/xc.

Is This Answer Correct ?    38 Yes 16 No

what is purpose of using reactor in substations...

Answer / jose

Due to the ferrantic effect the receiving end voltage is
greater than sending end voltage to avoid this problem we
useing the reactors(may be used in reactors 440kv
substation)
