Harmonic mitigation

Optimize harmonic mitigation 

Mitigating harmonic influence while ensuring your system operates as efficiently as possible can be a struggle.

At Danfoss Drives, we’ll help keep your energy gains in the green by delivering a harmonics solution designed for your business — and system.

How can harmonics interfere with your system?

Harmonics are voltages and currents which have frequency components that pollute the pure sinusoidal waveform in an AC circuit, ultimately distorting the main voltage. To further complicate matters, the greater the number of on-site power electronic switching devices you have, the greater the degree of distortion. However many you have, the results are the same: harmonic interference influences reliability, increases costs and affects overall product quality.

And though these issues are widespread, the challenges they present — and the measures needed to solve them — differ from system to system.

What happens when you take no action?

Excessive harmonic distortion of the mains supply implies the source not only carries 50 Hz or 60 Hz components, but those of a higher frequency. These components cannot be utilized by electrical equipment and thus, the effects of harmonic distortion can be severe:

Limited supply and network utilization
Increased losses due to unplanned downtime, control system malfunctions, and lower durability
Pulsating and reduced motor torque
