Size the series reactor for a power-factor capacitor bank tuned below a chosen harmonic. Enter the bank rating, system voltage and frequency, and the tuning order.
Tuning order is set below the harmonic to be blocked — common values are 3.78 (7%), 4.2 (5.67%) and 4.7 (4.5%).
The reactor is sized so the series capacitor-reactor circuit resonates at the entered tuning order, derived from the capacitor reactance at the stated voltage and frequency. Results assume a balanced linear system and do not account for capacitor tolerance, reactor tolerance, saturation, temperature, or system source impedance.
