NMi issues first Power Quality certificate

Half a year ago, during the European Utility Week 2015 in Vienna, NMi proudly announced a new service: testing power quality meters in accordance with IEC 61000-4-30 Edition 3. Last week, a great milestone was reached. The first power quality meter has been certified!

The certified meter is a Siemens SYCAN Q100, class A. The functional tests and uncertainty requirements that have been applied are stated in IEC 62586-2. The meter was exposed to all power quality phenomena that are listed in the IEC 61000-4-30 document. Think of voltage dips, interruptions, fluctuations, interharmonics, flicker and other phenomena.

IEC conformity
Monitoring the power quality is of the utmost importance to utilities. They can suffer considerable financial loss and credibility towards their customers when distortions take place. If all power quality meters in a grid operate in exact conformity with IEC 61000-4-30, they will measure the power quality phenomena in the same way. It is therefore obvious that both manufacturers of power quality meters and utilities are interested in this new testing service. At the moment, multiple power quality projects are running at NMi. The certificate for Siemens is the very first one that has been issued. We hope to help many other clients with the certification of their power quality meters too.

European Utility Week 2016
Of course we will be at the European Utility Week 2016 in Barcelona to answer all your questions about power quality measurement. Please drop by at booth 3H111 if you want to learn more, or send an email to our senior approval expert Mr. Henri Schouten: hschouten@nmi.nl
