Design and Implementation of a Three-Phase Analyzer in a Free Software Platform for Power Quality Measurement at Industrial Activities

Abstract:

Power quality analyzers are instruments that have various residential and commercial applications. These electrical devices measure various variables from basic quantities such as voltage, current or power to complex parameters such as harmonic content or power factor. Energy analyzers are too expensive instruments due to the high technological development involved in their manufacture. For this reason, this article shows an alternative in which a three-phase energy analyzer was designed and built with basic characteristics for measuring energy parameters. The energy analyzer was built with a RASPBERRY PI 4 platform in which voltage and current sensors were implemented to measure energy at different loads. The final prototype was validated with the use of standardized laboratory instruments and the utilization of different electrical loads to be able to size the scope to which the analyzer can be used.
