The Schaffner Group, headquartered in Switzerland, has released SchaffnerPQS3, an updated version of its power quality simulator. Using the free SchaffnerPQS3, power quality topics such as harmonics caused by nonlinear loads can be quantified and documented. Realistic performance simulations of mitigation tools such as Schaffner ecosine power quality filters can be conducted


In addition to the updated and more intuitive new design, SchaffnerPQS3 is more robust, reliable, flexible and easier to use in comparison to earlier versions and it features the following upgrades;


Back-end simulation engine power and accuracy improvement

Refreshed new GUI design, wiring by left click, delete function by delete button

Share projects with colleagues/partners by simply copying the URL link

Even more accurate AHF simulation model

Generator model included

Customer specific AC line chokes functionality now available

Schaffner 18-pulse autotransformer – “Mitigator” included


The updated SchaffnerPQS3 is particularly suitable for systems with variable speed drives. Once a user sets up an account, they can immediately start using this powerful tool free of charge.


SchaffnerPQS3 can be accessed via pqs.schaffner.com or www.schaffner.com
