dqa.tasks.transformations.PhaseSequence#

class dqa.tasks.transformations.PhaseSequence(phases_axis: int = 1, coefficients_axis: int = 2, coefficient_range: List[int] | None = None, **kwargs)#

Determines the phase sequence from the fourier coefficients of a three-phase alternating current.

The input is an array containing the Fourier coefficients for each of the three phases. For a 2D-array (one axis for the time, one axis for the phases), it returns -1/0/+1, while +1 stands for the phase order 1-2-3. For arrays with more axes, it performs this action for each coordinate along the other axes separately.

Parameters:
  • phases_axis (int, default=1) – The axis along which the phases are arranged.

  • coefficient_axis (int, default=2) – The axis along which the Fourier coefficients are arranged.

  • coefficient_range (list of ints, default=None) – If set, only the coefficients in the range defined by the elements are considered.

Methods

finish()

Can perform actions that are required to clean up after the task has finished, e.g. close network connections etc.
