Short-circuit test results determine mesh impedance parameters. They include load losses and leakage impedances. For three-phase windings, the excitation can be positive sequence (the default) or zero sequence. There must be at least one grounded winding.Short-circuit test results determine mesh impedance parameters. They include load losses and leakage impedances.

(Constructor)

Initialises a new 'ShortCircuitTest' instance.

Parameters:

lossZero - Load losses from a zero-sequence short-circuit test.
leakageImpedance - Leakage impedance measured from a positive-sequence or single-phase short-circuit test.
loss - Load losses from a positive-sequence or single-phase short-circuit test.
groundedEndStep - Tap step number for the grounded end of the test pair.
leakageImpedanceZero - Leakage impedance measured from a zero-sequence short-circuit test.
energisedEndStep - Tap step number for the energised end of the test pair.
GroundedEnds - All ends short-circuited in this short-circuit test.
EnergisedEnd - Transformer end that voltage is applied to in this short-circuit test. The test voltage is chosen to induce rated current in the energised end.

Overrides: object.__init__
