Power-factor correction
continues from lesson 4 — values defined earlier in the course stay live here
That 0.86 power factor means the line carries current that does no work. A capacitor bank supplies the reactive part locally, unloading the wiring upstream. The size needed to reach a 0.95 target:
= 2181.4 W capacitor bank size (VAR)
Where next: the Σ library has three-phase power, motor current and RLC impedance formulas — and try p_poles := 2 above to see the whole worksheet re-derive a 3600 rpm machine.
