electricpy.fault.ct_satratburden(Inom, VArat=None, ANSIv=None, ALF=20)[source]

Electrical Current Transformer (CT) Saturation at Rated Burden Calculator.

A function to determine the Saturation at rated burden.

\[V_{saturated}=ALF*\frac{VA_{rated}}{I_{nominal}}\]

where:

\[VA_{rated}=I_{nominal}*\frac{ANSI_{voltage}}{20}\]
Parameters:

  • Inom (float) – Nominal Current

  • VArat (float, optional, exclusive) – The apparent power (VA) rating of the CT.

  • ANSIv (float, optional, exclusive) – The ANSI voltage requirement to meet.

  • ALF (float, optional) – Accuracy Limit Factor, default=20.

Returns:

Vsat – The saturated voltage.

Return type:

float
