MV current limiting reactors
Function
Air-core reactors type ED3PH are inductive elements connected in series with the current path to limit short-circuit currents. The limitation of short-circuit current is achieved by introducing additional reactor reactance into the circuit, increasing its overall value. During normal operation, line current flows through the reactors, resulting in certain power losses and voltage drops. Reducing the short-circuit current allows for the selection of switchgear, cables, and electrical equipment with lower short-circuit withstand capability.
