OMICRON electronics

It is the pressure being exerted by network agencies, network end customers and also distributed network operators that is driving forward the expansion of a seamless system for monitoring power quality in high and medium-high voltage networks. Class A PQ analyzers are used for this per IEC 61000-4-30. The IEC 61000-4-30 standard defines the methods of measurement and the interpretation of the measurement results. The basis for the assessment of power quality is the ability to determine it accurately. The regular testing and calibration of these devices presents manufacturers, commissioners and equipment maintenance personnel with new challenges.

The IEC 61000-4-30 standard describes all PQ phenomena that a PQ analyzer must be able to detect and classify. It is these phenomena that OMICRON’s CMC 256plus test system in conjunction with the software module "PQ Signal Generator" is able to reproduce with a high degree of precision. It provides every type of signal – from a flicker, through unbalance and harmonics, right up to transient short-time dips.
