Compensation of reactive power merely by capacitors without any reactors is not always permissible in networks to which generator of harmonics, such as static converters, are connected. These harmonics can lead to serious problems such as overheating of cables, motors and transformers, tripping of circuit breakers, capacitor overloading and failures, excitation of network resonance, etc.
Harmonic filter equipment, consisting of a capacitor and a series reactor, are generally recommended when converter loads, which generate harmonics, exceed about 15 to 20% of the total consumer load. These filter circuits offer major advantages to the system, such as the protection of the capacitors against resonances alongside its high frequency currents and filtering properties.
