IEC 61000-4-30 StandardPower Quality Measurement Methods
Class A performance Used, where precise measurement is necessary
Contractual applications Verification compliance with standard Resolving disputes
Class B performance Low uncertainty
Statistical surveys Trouble shooting
Page 30April 2011
Class A requirement Aggregation algorithm Time clock uncertainty (at least 1s/24h) Flagging concept to avoid counting events several timesPower quality parameters Power frequency Voltage and current magnitude Flicker Voltage Dips, interruptions, swells Current inrushes Voltage unbalances Harmonics/Interharmonics Voltage signals Transients
