Ensure power quality! These claims are becoming stronger and louder. This is confirmed by utilities, industrial companies, but also by many of the electrical specialists who are increasingly confronted with the topic on the part of their customers. The question often arises as to which measuring device should be used, with which expertise and with which budget.<\/p>\n

Ensure the quality of the network for industrial needs. This is now offered by the LINAX PQ1000 series power analyzer according to IEC61000-4-30 class S<\/strong>. The measuring instrument is specially designed for the area of “Demand Side Power Quality” (DSPQ)<\/a>. There you will find the process for securing the power quality on the consumer side (according to the PoCC<\/a> as per IEC TR 63191).

But why class S and not class A<\/h3>\n

\"Standards\"<\/a><\/p>\n

Measuring instruments according to IEC 61000-4-30 Class A<\/strong><\/a> generally provide measured values that are comparable across measuring instruments and manufacturers. In case of legal cases, class A is mandatory and is particularly relevant for distribution system operators.<\/p>\n

IEC 61000-4-30 class S<\/strong><\/a> power quality analysers 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 are no potential disputes there. Thus, comparable measurements are also not mandatory. The performance requirements for Class S are less stringent than for Class A. Among other things, this also results in a lower price. They are often used in industrial and supply engineering at the IPC<\/a>(according to IEC [TR] 63191 this is the network distribution according to the Point of Common Coupling (PoCC)). Even in data centers<\/a>, these are strongly recommended according to EN50600-2-2:2019-08 [Kapitel 6.2.3 Spannungsqualit\u00e4t] within the infrastructure.<\/p>\n

Ensuring power quality with certification even for class S<\/h3>\n

A very important criterion for correct and repeatable measurement of power quality is compliance with standards for the measurement procedure<\/a>. These are not to be confused with power quality compliance standards. For this reason, class S measuring devices should also be certified. With the LINAX PQ1000, this is ensured on the basis of the big brothers LINAX PQ3000 & PQ5000 by METAS, the Swiss Federal Institute of Metrology. Swiss precision.<\/p>\n

Ensuring network quality with the highest standards of cyber security<\/h3>\n

\"Cyber<\/a><\/p>\n

The topic of cyber security<\/a> is also becoming more and more important due to the constantly growing networking. Especially in the areas of power distribution, whether in public or private networks. Due to the threat situation<\/a>, effective cyber security is essential. To this end, the LINAX PQ1000<\/strong>offers many of the same effective protective features as its larger siblings. These include:<\/p>\n
