POWER FACTOR CORRECTION IN HIGH-THD ENVIRONMENTS: DESIGN CRITERIA AND OPERATIONAL SAFETY

High harmonic distortion can compromise power factor correction systems. Discover how detuning reactors, proper protection and careful design help prevent resonance, overheating and equipment failures.

In industrial installations with widespread inverters, UPS systems and electronic loads, high harmonic distortion can make traditional power factor correction systems vulnerable to overheating, premature capacitor ageing and resonance.

Ensuring safe and reliable operation requires more than improving power factor. Proper system design must consider THDi and THDv levels, harmonic spectra, load variability and network characteristics.

Detuned capacitor banks equipped with blocking reactors help reduce resonance risks and protect components. In more demanding environments, active harmonic filters or hybrid solutions may be necessary.

Ortea Next offers dedicated power factor correction solutions, including the FH and FV ranges designed for high-THD applications.

Correct component sizing, thermal management, suitable protection devices and preventive maintenance are essential to maintaining long-term reliability.
