modelVmeter
Voltage meter, 3-phase dqo
Extends from Partials.Meter1Base (Meter 1 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:
v voltage phase-to-ground vpp voltage phase-to-phase
Optional output variables:
v_abc voltage phase-to-ground, abc-inertial system vpp_abc voltage phase-to-phase, abc-inertial system v_norm norm(v) alpha_v phase(v)
