POWER QUALITY ASSURANCE NOW ALSO AVAILABLE IN SMALL FORMAT: LINAX PQ1000 MEASURES POWER QUALITY FOR INDUSTRIAL REQUIREMENTS ACCORDING TO CLASS S

Good cybersecurity built into each individual measuring device is now indispensable.

Assure power quality! Demands for power quality assurance are growing stronger and louder. We hear this confirmed by utilities, industrial companies, but also by many electricians who are increasingly confronted by this issue when dealing with their customers. Very often questions then arise as to which measuring instrument should be used, the level of skill and the size of the budget required.

ower quality assurance for industrial needs. Power quality assessment according to IEC61000-4-30 class S is now provided by the LINAX PQ1000 power analyser series, whereby the measuring instrument is especially designed for analysing demand side power quality. The power quality assurance process on the demand side (after the PCCas per IEC TR 63191) is described here: “Demand Side Power Quality” (DSPQ)”.

But why class S and not class A? Measuring instruments according to IEC 61000-4-30 Class A, basically provide measured values that are comparable across measuring instruments and manufacturers. In case of legal disputes, class A is mandatory and is especially relevant for distribution system operators. Power quality analysers according to IEC 61000-4-30 class S are intended for basic/advanced power quality analysis and provide useful monitoring data. Instruments that meet Class S performance requirements are used for statistical power quality surveys and other applications and measurement services. There is no potential for disputes. This also means that no mandatory requirement for comparative measurements. The performance requirements for Class S are less stringent than for Class A. This results among other things, in a lower price. In industrial and utility applications, they are often used in the IPC (according to IEC [TR] 63191, this is the power distribution network after the Point of Common Coupling [PCC]). Even in data centres, they are
