Current limiting reactors They are series reactors that reduce the short circuit currents in the power system. The advantage of their use is that the circuit breakers in the network systems with lower circuit breaking capacity are less expensive. Another use is reducing inrush current in the motors. Dry type are used as alternative to the oil filled type and when there is enough surrounding space to keep magnetic field limits below maximum limits permitted by laws and regulations. Another restriction in selecting oil or dry type reactors are the polluted conditions, critical at the highest levels. Phases coils can be arranged as three-phase or single-phase units. Neutral earthing reactors They are single phase units used to ground neutral terminals in MV networks, directly or by impedance. They can be realized both dry type and liquid filled.
