Meter Split
This section describes the three-phase meter split component from the Microgrid library.
The Meter Split is a component located in the Microgrid Library. The component's icon and properties window are shown in Table 1. The Meter Split is a masked bus split that is compatible with the signal processing outputs of the Three-phase Meter. Its inputs are vectors of fixed size, while its outputs are scalar values. Its size and number of output ports are changed dynamically based on the selected measurements.
