'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)
