How to choose? guidelines
Jinneng electric integrated harmonic suppression smart capacitor application guidelines as follows:
Fifth harmonic (250Hz):
Typical sources: Frequency converters (VFD), switching power supplies, electric arc furnaces.
Reactance rate selection: The 7% reactor reduces the tuning frequency to approximately 189Hz, avoiding resonance with the 5th harmonic.
Third harmonic (150Hz):
Typical sources: Single-phase nonlinear loads (such as computers, energy-saving lamps).
Reactance rate selection: The reactance rate is set at 14%. The reactor is tuned to a frequency of 133Hz to suppress the amplification of the third harmonic.
●Harmonic measurement priority:
Use the power quality analyzer to measure the system's THD% (total harmonic distortion rate) and the content of each harmonic.
If the proportion of the 5th harmonic is greater than that of the 3rd harmonic, select an 7% reactance rate; if the 3rd harmonic is dominant, select a 14% reactance rate.
●Capacitance matching:
7% reactor: Suitable for standard capacitors (such as a 30kvar capacitor paired with a 2.1mH reactor).
14% reactor: Requires higher voltage capacitors (due to greater voltage drop of the reactor).

Attention:
●Avoid overcompensation:
A 14% reactance rate will significantly increase the system impedance, which may result in excessive voltage drop (the bus voltage needs to be verified).
●Mixed harmonic environment:
If the 3rd and 5th harmonics are both high, a multi-stage filtering scheme (such as 7% reactor + active filter) should be adopted.
