The increasing use of equipment with non-linear voltage-current characteristics can raise concerns or problems in power quality delivery, including phenomena as defined in EN 50160: - voltage fluctuation (flicker)
- voltage unbalance
- voltage sags or dips
- transient overvoltage
- harmonics and interharmonics
KEMA intends to provide effective solutions to power quality and harmonics challenges before they become a problem for network operators and consumers. Our services include: - performing studies and analyses of new installations according to standards
- measuring and assessing power quality problems
- providing solutions and minimizing power quality problems in compliance with international protocols and standards
- testing and calibration of PQ monitors
- designing monitoring systems and selecting fitting measurement systems
- assisting clients with product design
- selecting power quality solutions
- providing professional training courses
Examples of our consultancy projects are: - the Dutch power quality monitoring project
- measuring harmonics through voltage transformers in HV systems
- harmonic Interaction between Large Numbers of Photovoltaic Inverters and the LV Network
- energy-efficient industrial transformers
- assessment of harmonic emission and voltage quality for 6 types of traction substations
