Multi Sensor

Multiphase sensor to measure current, voltage and power

 Description The Multi Sensor component measures currents, voltages, and instantaneous electrical power of a multiphase system, using separate voltage and current paths. The plugs of the voltage paths are pv and nv, the plugs of the current paths are pc and nc. The internal resistance of each current path is zero, the internal resistance of each voltage path is infinite.
 Equations $i={i}_{\mathrm{pc}}=-{i}_{\mathrm{nc}}$ ${i}_{\mathrm{pv}}={i}_{\mathrm{nv}}=0$ $v={v}_{\mathrm{pv}}-{v}_{\mathrm{nv}}$ ${v}_{\mathrm{pc}}={v}_{\mathrm{nc}}$ ${\mathrm{power}}_{k}={v}_{k}\cdot {i}_{k}$ $\mathrm{powerTotal}=\sum _{k=1}^{m}{\mathrm{power}}_{k}$
