PQA certification: 61000-4-30 Ed.3.0

We would like to inform you that our selected power quality analysers (MI 2893 - Class A / MI 2892 – Class A; MI 2885 – Class S) are finally certified in accordance with the latest international standard – 61000-4-30 Ed.3.0. Certification procedure was performed by Power Standards Lab Inc. (PSL), an internationally recognized power quality laboratory, in compliance with IEC 62586-2 “Power quality measurement in power supply systems – Part 2: Functional tests and uncertainty requirements”.
The IEC 61000-4-30:2015 standard defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results.
Measurement parameters include:
  • Power frequency
  • Magnitude of supply voltage
  • Flicker
  • Supply dips/swells
  • Voltage Interruptions
  • Unbalance
  • Harmonics
  • Interharmonics
  • Mains signalling
  • Under- and over-deviation
New certified functionality in Ed. 3:
  • Rapid voltage changes
  • Magnitude of the current
  • Current unbalance
  • Current harmonics
  • Current interharmonics
  • Recording of current along with voltage during events
