MV Current limiting reactors LV to 2000A ED3PH

Function
Current limiting air reactors are inductive components connected to the main supply. They act as an additional reactance installed in series to the current path thus short-circuit current value is lowered.
During regular operation (in no fault condition), linear current flows through the reactor which generates a voltage drop and small power loss.
Reducing value of the short-circuit current allows the selection of switchgear, cables and electrical equipment with reduced short-circuit strength.

Benefits	Application
Reduction of short-circuit at the point of common coupling Use of devices with lower short-circuit strength Reduction of minimum cable cross-section required by short-circuit conditions	Power supply systems with cogeneration units Switchgears located near the high power generation units MV networks
