The following issues are related to poor power quality caused by harmonic distortion:
Reduce risk using harmonic mitigation
Have you experienced
The cause is often poor network quality due to harmonic distortion. Harmonic distortion causes damage to critical equipment leading to failures.
Adding drives (VSDs) to your system can improve network quality, massively reduce energy consumption, and manage driven loads to ensure breakdowns are minimized with good maintenance planning. Managing harmonic distortion using drives brings stability to the electrical grid and reduces outages.
The whole topic of network quality and how it impacts greenhouse gas accounting can be daunting. Luckily you don’t need to be the expert. Danfoss experts stand ready to support your business with expert advice and VSD solutions for energy savings and cost-effective harmonic mitigation.

Harmonic distortion and harmonic distortion generators causes poor network quality which is a big factor in wasting greenhouse gases (GHGs).
We can help you to optimize GHG accounting with good advice on
Are you engaged in carbon accounting or GHG calculations to meet GHG accounting standards such as the Greenhouse Gas Protocol? Do you set net zero targets and have ambitions to make your company more environmentally friendly?
Designing early for low total harmonic distortion mean smaller transformers, generators and switchgear components, which contain less materials, are lighter to transport and take less energy to manufacture.
Less fuel and energy is needed to operate the plant when VSDs are employed as widely as possible, compared with poorer control strategies, offsetting initial capital cost. This results in fewer greenhouse gas sources.
Learn how drives influence Scope 3 upstream emissions.
VSDs ensure minimum waste from the plant due to minimized breakdowns and downtime. Drives offer 10-year operating life without maintenance, and fewer plant breakdowns with smart condition-based monitoring to protect driven loads and the wider process.
When smaller high-capital equipment is purchased in the beginning, there is less waste to recycle when plant reaches end of life. Altogether, this reduction supports reduced carbon emissions.
How drives impact Scope 3 downstream emissions
VSDs always control the process to the optimal level for efficiency , throughput and quality. Controlling fans, pumps, and compressors brings the highest energy saving (2-60%), although conveyors and cranes and other applications also benefit greatly. Connect VSDs with motors of the highest efficiency class to maximize the benefits of both technologies, to reduce carbon emissions and other greenhouse gas emissions.
Learn how drives influence Scope 2 emissions.
VSDs ensure the plant operates and produces output most efficiently, ensuring lowest possible direct emission from the processes. Emissions can be measured and connected back to the VSD to manage setpoints of emissions directly and reduce waste during the manufacturing processes. VSDs can be used to treat unwanted greenhouse gas emissions emissions to reduce their impact.
Discover how drives impact Scope 1 emissions.
Harmonic distortions affect the mains power network, causing poor power quality, unreliability, and potential equipment damage. Danfoss can help you to reduce the effects of harmonics.
Harmonic mitigation reduces unwanted frequencies in electrical systems, preventing equipment damage, and improving power quality and efficiency.
