Mains quality measurement in small format 96×96

Measure and ensure network quality! These demands 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 this topic by their customers. The question often arises as to which measuring device should be used, with which level of expertise and with which budget.

Ensuring power quality for industrial needs. This is now offered by the power analyzer of the LINAX PQ1000 series according to IEC61000-4-30 class S. Thereby the measuring instrument is especially designed for the area of “Demand Side Power Quality” (DSPQ). There you will find the process for safeguarding the power quality on the consumer side (according to the PoCC as per IEC TR 63191).

But why class S and not class A

Measuring devices according to IEC 61000-4-30 Class A basically provide measured values that are comparable across measuring devices and manufacturers. In case of legal cases, class A is mandatory and is especially relevant for distribution system operators.

Power quality analyzers 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 are no potential disputes there. Thus, there is also no mandatory requirement for comparable measurements.

The performance requirements for Class S are less stringent than for Class A. This results, among other things, in a lower price. They are often used in industrial and utility applications at the IPC (according to IEC [TR] 63191, this is the network distribution according to the Point of Common Coupling (PoCC)). Even in data centers, they are strongly recommended within the infrastructure according to EN50600-2-2:2019-08 [Chapter 6.2.3 Voltage quality].

Mains quality measurement with certification even for class S

A very important criterion for correct as well as repeatable measurement of power quality is compliance with standards on the measurement procedure. These should not be confused with the power quality compliance standards. For this reason, class S measuring instruments 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.

Simply Swiss precision.

Measuring network quality with the highest standards of cyber security

The topic of cyber security is also becoming more and more important due to the constantly growing networking. Especially in the areas of energy distribution, whether in public or private networks. Due to the threat situation, effective cyber security is essential. For this purpose, the LINAX PQ1000 offers many of the effective protection features as its big siblings. These include:

Role-based access rights (RBAC)
Transport encrypted websites (https)
Client whitelist for access limitation of end devices
Audit log for seamless monitoring of changes and operations
Certified firmware updates
Data logger as redundancy outside the IT system

Designs of the LINAX PQ1000

The measuring instrument, also called Power Quality Instrument (PQI) according to IEC 62586-1/2 for the analysis of power quality in power supply systems, is available in various options. With the common 96x96mm form factor, the meter fits well everywhere. Whether as panel mount with TFT display or for DIN rail mounting with or without TFT display. All variants are possible and offer high flexibility. Added to this is the simplest operation and communication via integrated web browser. Without additional software, operation, parameterization as well as monitoring is made child’s play.
