Oil Filled Magnetically Shielded Current Limiting Reactors


Current Limiting Reactor (CLR) is one of the most effective short circuit current limiting devices. It reduces stresses on busses, insulators, circuit breakers and other high voltage devices. Use of CLR is the most practical and economical approach at current limiting.

Current Limiting Reactors should be placed where 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.

They are also used as load sharing reactors for balancing the current in parallel circuits. These reactors are designed in a way to withstand the rated current continuously and fault currents for a certain period of time.

Oil filled magnetically shielded reactors provide best thermal performance where dimensions constraints are quite strict. Also, due to magnetic shield capability best EMI performance is enabled. This special type of current limiting reactor is fully tested to ensure its quality and durability. This product is highly requested by the customers for its best performance. It can be used in several industries for different applications.
