ICAR FH20 / FH30 detuned reactive power compensation units with reactors
Country: · Model: ICAR FH20 / FH30
ICAR FH20 and FH30 are reactive power compensation units with blocking reactors for networks with a high level of harmonics from frequency converters and rectifiers. The capacitors are rated for 550 V, and the tuning frequency is 180 Hz in FH20 and 135 Hz in FH30. The permissible THDIR is 100 %.

Description
The series reactor shifts the circuit resonance below the harmonic frequencies, so the capacitors are not overloaded by the currents generated by converters and rectifiers. A permissible THDIR of 100 % means that the unit works even in a network where the harmonic current is comparable to the fundamental. All versions are equipped with 550 V capacitors. A 400–415 V, 50 Hz network is the base case, and for 60 Hz the 230, 400 and 480 V versions are made. The range covers MICROfix, MINImatic, MULTImatic and the rack-mounted MULTIrack, designated .S.
How to choose
The tuning frequency is chosen by the harmonic spectrum in the node. FH20 is tuned to 180 Hz, FH30 to 135 Hz. If there are few harmonics and THDIR does not exceed 27 %, VP10 or VP20 without reactors is enough. For THDIR up to 12 %, 20 % and 27 % there is the HP10, HP20 and HP30 series with 415, 460 and 550 V capacitors. The FV25 model is also tuned to 180 Hz but has 460 V capacitors.
