The decline in quality of power is a big issue due to increase in the usage of power electronics that uses inverters, an increase of unbalanced loads like large furnaces or rectifiers, and typically complex power distribution due to an increment in power network interconnections for new energy plants, etc. Inadequate power quality induces potential problems in receptacle/transmission devices and electronic apparatus malfunctions.

Power supply network issues that are induced by inadequate power quality are a frequent issue for both electric power providers and consumers. Nevertheless, it is not simple to tell if the source of inadequate power supply quality is at the provider’s side or the consumer’s system. Depending on this arrangement, power quality measurement is required to know the actual source of power quality issues as well as to treat and assess for efficient countermeasures.

In this course, you’ll learn a step-by-step power quality evaluation process. You’ll learn why and how we measure power quality. You’ll learn the basic arrangement of a digital measuring device and the parameters to measure in a power quality assessment. You’ll learn the purpose and operating principles behind transient recorders, harmonic analysers and combination devices. You’ll learn how measuring instruments are used and connected. And you’ll learn how recorded values are statistically analysed.
