Meter Split

Description of the Meter Split component capable of selecting specific measurements from the three-phase meter component.

Component Introduction

Figure 1. Meter Split component icon

The Meter Split component is part of the fundamental set of measurements available in Schematic Editor. Meter Split is a masked bus split that is compatible with the signal processing outputs of 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.
