IEC 61000-4-30 IEC 61000-4-30 defines measurement methods for 50 Hz and 60 Hz power quality instruments. Power Standards Lab was deeply involved in developing this standard, and continues to guide its on-going revisions and updates.
PSL offers a complete test and verification service for this standard. All instruments that meet the Class A performance requirements of this standard will, when connected to the same signals, will produce the same results. Instruments that meet the Class B performance requirements will produce useful, but not necessarily accurate, results. |

| This standard ensures that different PQ instruments use the same definitions, and measurement techniques, for various power quality parameters: sags/dips, swells, frequency, harmonics, flicker, etc. Older, non-compliant instruments may use their own definitions. As a result, two non-compliant instruments may produce very different readings for the same event. | |
