Loads operated by electronic devices are increasingly adopted in more and more industrial and commercial applications such as: Variable Speed Drives, rectifiers, UPS systems, DC power supplies, welding machines, computers, TV, energy efficient lamps, photocopiers.

These loads generate waveform distortions that become threat for network components.In particular voltage and current harmonics, where the latter is the more dangerous, generate a series of problems, like:

• Cable overheating.
• Undue tripping of circuit breakers.
• Blowing of fuses.
• Capacitor overloading and network resonance.
• Neutral cable overload.
• Transformer premature ageing.
• Electronic appliances disturbance.

These effects are seldom related to harmonic current and voltage distortion, while effective remedy for harmonics are passive and active filters.Active filters achieve much higher levels of efficiency in harmonics cleaning the first does not.

ICAR has developed the ACTIVEmatic FA30 ACTIVE HARMONIC FILTER to combine a high level of efficiency with flexibility of installation.
