Harmonic Filters

Power quality is a significant concern for today's manufacturing and power generation facilities. Finding the right solution for unbalanced loads is important. Two major power quality issues are harmonic distortion and reactive power generated by a low power factor.

Devices such as variable frequency drives, servo drives, LED light drivers and other devices that rectify AC to DC can generate harmonic distortion. It is important to limit the distortion under a certain level to reduce effects on other equipment in a facility.

Enerdoor passive harmonic filter and line reactor series meet any type of requirement in terms of harmonic reduction and cost. Passive harmonic filters and line reactors are recommended for single-drive applications and are sized by the total current.

As an alternative, the active harmonic filter works in parallel and compensates current for single or multiple-load applications operating under varied loads. They may be used for single applications or an entire facility.

Benefits of Harmonic Solutions:

• Ensure IEEE-519 compliance
• Reduce harmonic distortion to <5% with an unbalanced voltage of 2.5%
• Limit distortion within a certain level to mitigate effects on other equipment
• Line reactors & passive harmonic filters for drive applications, sized by total current
• Active harmonic filters work in parallel & compensate for load applications
• May be used for individual applications or an entire facility
