MAGNETICALLY SHIELDED AIR CORE CURRENT
LIMITING REACTORS
A Current
Limiting Reactor (CLR) is one of the most effective short circuit current
limiting devices. It reduces stress on busses, insulators, circuit breakers and
other high voltage devices. Use of a CLR is the most practical and economical
approach to current limiting.
Current Limiting
Reactors should be placed in a distribution or transmission system where a
potential short circuit current has been calculated to exceed the interrupting
rate of the associated switchgear. The inductive reactance is set low enough
for an acceptable voltage drop during normal operation, but high enough to
restrict a short circuit to the rating of the switchgear.
CLRs are also
used as load sharing reactors to balance the current in parallel circuits. They
are designed to continuously withstand the rated current and fault currents for
a limited period of time.
Magnetically shielded air core reactors provide the best thermal performance in situations of strict dimensional constraint. Additionally, due to magnetic shield capability, best EMI performance is enabled. This special type of current limiting reactor is fully tested to ensure quality and durability. It can be used in several industries across applications and is one of our most-often requested products, due to exceptional performance capability.
