electricpy.pfcorrection(S, PFold, PFnew, VLL=None, VLN=None, V=None, freq=60)[source]¶

Power Factor Correction Function.

Function to evaluate the additional reactive power and capacitance required to achieve the desired power factor given the old power factor and new power factor.

Parameters:¶

S : float¶

Apparent power consumed by the load.

PFold : float¶

The current (old) power factor, should be a decimal value.

PFnew : float¶

The desired (new) power factor, should be a decimal value.

VLL : float, optional¶

The Line-to-Line Voltage; default=None

VLN : float, optional¶

The Line-to-Neutral Voltage; default=None

V : float, optional¶

Voltage across the capacitor, ignores line-to-line or line-to-neutral constraints. default=None

freq : float, optional¶

System frequency, default=60

Returns:¶

• C (float) – Required capacitance in Farads.

• Qc (float) – Difference of reactive power, (Qc = Qnew - Qold)
