modelImeter

Current meter, 3-phase dqo

Extends from Partials.Meter2Base (Meter 2 terminal base, 3-phase dqo).

Information

'Meters' are intended as diagnostic instruments. They allow displaying signals in alternative representations, both in SI-units or in 'pu'.
As they use time-dependent coordinate transforms, use them only when and where needed. Otherwise use 'Sensors'.

Output variables in the chosen reference system:

  i          current term_p to term_n

Optional output variables:

  i_abc      current term_p to term_n, abc-inertial system
  i_norm     norm(i)
  alpha_i    phase(i)
