Get the clarity you need to select, specify and design the right harmonic filter for your specific power quality challenges.
Simulate grid voltage harmonics and specify a PowerAct Active Filter for your precise application. Input your own harmonic measurements, load characteristics and operating conditions to see how the load profile shifts, and how those changes influence optimal filter design.
Launch Sizing Tool
See how your actual distortion levels drive key filter parameters. Generate specs you can use to compare harmonic filter options, validate performance or inform your application design.
Launch CalculatorNot at all. Anyone can use the calculators, and the results are yours to apply as you see fit. Of course, if you’d like a filter built precisely to your specifications, Powerside is ready to help.
For best results, gather your load characteristics, power factor, short circuit information, bus voltage and any known sources of distortion. The more accurate your inputs, the more precise the calculators’ outputs.
If you’re unsure of any particular data item, simply click the specific input to reveal more in-depth information on what it means and what it should be used for.
Yes. Use them for design-phase planning, retrofit evaluations, troubleshooting and performance validation.
The calculators use Powerside’s engineering-grade algorithms based on industry standards and years of field-tested filter designs. Outputs are intended to guide engineering decisions and support formal specification work.
You can use the calculators for however long you need. After an idle period of 5-10 minutes, the system will automatically log you out to free up access for others.
The calculators can only support a limited number of users at a time. If you receive an error, please wait a moment and try again.
Yes. Each calculator allows you to print and save your calculations so you can reference them later.
Absolutely. Reach out to us directly and we’ll schedule a walkthrough with one of our highly skilled engineers.
