In this document, the Multisim (LabVIEW based) instruments used for power applications are presented.
Each instruments is demonstrated along with an example circuit.
1. Power Quality Measurement Instrument
Download this instrument that takes various single phase poqwer quality measurements on an input voltage and current of a signal, such as:
- The RMS voltage
- The RMS current
- The instantaneous RMS power
- The reactive and apparent power
- The crest factor
- The power factor
Example Circuit (drag and drop snippet png file into Multisim):
2. Load Controler
Download this instrument that allows the user to adjust the load and view the corresponding voltage and current. With this instrument, you cancustomize a pattern for the load value and see in simulation how the voltage accross and the current through react to these changes.
Example circuit:
