CURRENT LIMITING REACTOR, KK-XX SERIES
Our new email address is quote@lcmagnetics.com
L/C Magnetics is a manufacturer of Current Limiting Reactors (CLR). Current-limiting reactors are series inductors intended to reduce the short circuit currents passing thru the circuit breaker in the power system. A higher voltage is developed across the CLR when the current thru the CLR increases.
A current-limiting reactor is used when the prospective short-circuit current in a distribution or transmission system is calculated to exceed the interrupting rating of the associated switchgear. The inductive reactance is chosen to be low enough for an acceptable voltage drop during normal operation, but high enough to restrict a short circuit to the rating of the switchgear. The amount of protection that a current-limiting reactor offers depends upon the percentage increase in impedance that it provides for the system.
The main motive of using current-limiting reactors is to reduce short-circuit currents so that circuit breakers with lower short-circuit breaking capacity can be used. They can also be used to protect other system components from high current levels and to limit the inrush current when starting a large motor.
The typical application of the CLR is shown below:
Three Air Core Inductors are required for one CLR system
