Harmonic resonance scan and passive filter design report
Power quality outputs THD, but there is no system harmonic-impedance scan, no resonance-risk assessment and no passive-filter selection assessment.
Pick a scheme first — then this column can calculate
This column runs the real engine on your project scheme, and there is none yet — that is why no calculation buttons are shown here (they are not broken). Start with any of the ways below; the fastest is the built-in example (one click, real parameters).
10 kV incoming (200 MVA short-circuit level) → 1250 kVA transformer (Dyn11) → LV main switchboard → busbar → 5 feeders plus a fire/emergency ATS branch. 1000 kW calculated load, cosφ 0.85, power-factor target 0.95.
Load the real example scheme and start calculating →The scheme and its parameters go straight into your browser; replace the data with your own at any time.
Calculator mode computes the few outputs that only depend on parameters you type in yourself. Anything that genuinely needs the whole system (full-network load flow, coupling with other devices) is shown as “needs a scheme” and no number is given.
Calculator mode is not available for this column yet — use one of the ways below.
Nothing is pre-filled and nothing is invented: leave a required field empty and the result area says “unavailable”.
In the studio, place devices, wire them and pick models — that becomes your project scheme (drawings / BOM / report can be exported).
Open the studio →Use the chat bubble bottom-right, or Contact us — we will set the example to your site parameters.
Note: every number comes from the engine. With no scheme, nothing is invented here.
