5T-Power Quality Measurements - Essential Theory

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.

This course is suitable for engineers with a desire to basic theory necessary for power quality measurements. Presented details cover issues related to power quality events and parameters, sampling techniques, basic principles of measuring devices, statistical techniques used for processing results, connection of measuring instruments and their features. Practical steps for measuring process are also mentioned.
