Answer / jeetendra verma

when a transmission line of EHV is charged at no load, the
charging current flow between all phases will create a
capacitve effect, resulting the receiving end voltage
become more than sending end voltage.Reactors which have
very high self inductance and negligible resistance
stablize the receving end voltage.

Answer / naresh

reactor is inductance conected in series with transmission
feeder to minimise the magnitude of fault current.i.e.
short circuit or earth fault.

Answer / paritosh singha

reactor is mainly used in high voltage long transmission
line (above 200km)to compensate the ferranti effect i.e to
minimise the capacitive effect.now a line should only have a
resistance in it.but due to long transmission capacitance
comes into effect.so to nullify it we add a specific
amount(say 50 mvr)of reactor in it.

Answer / santosh

Reactors are mainly used to limit,the flowing of very large short circuit current during fault. it main function is to protect the plant, by limiting the amount of power that can flow into the faultier part by all other parts of the system.Eg.,Generator reactors,feeder reactors,busbar reactors,etc.

Answer / elaya

Reactor is a device like capacitor.which is normally
connected on high voltage swithchyard maximum 400kV in the
account of compensate reactive power on station in during
night hours (low power supply-due to industrial shut down
at night). we can classify it into two types 1.Switched
reactor 2.non swithched reactor.

simply it is power compensating device.

Answer / dolnarayan patel

Energy storing element in ac ckt. Used to avoid sudden
direction change of current and also to limit heavy flow of
current.

Answer / iddrisu habilah

Reactors are used to limit over voltages in a network
system.It is also use to absorb reactive power so that
active power can be transmitted over the network.

Answer / sumit sail

In order to limit the short circuit currents to a value which the circuit breakers can handle, additional reactances known as reactors.

Answer / विशाल खरवा�

Reactor is a very high inductive coil which has approx zero power losses and high reactance. Which generally used with EHV transmission lines.
Application–
1. Reactor is used to minimise the faulty current of transmission line.

2. Reactor is used to compensate the ferranti effect and capacitive effects.

3. Reactors used for connecting two lines. I.e. as a tie line connector.

4. Reactor opposes the change of faulty and dangerous current.👍👍

Answer / s.elangovan

reactor is a one of the current limit system in HT
Capacitor and HT transmission line.

should %impedance be high or low in a power transformer? if so why?
