techniques - Power quality measurement methods,
 IEC 61000-4-7:2007 – Electromagnetic compatibility (EMC) – Testing and Measurement
Techniques - General Guide on Harmonics and Interharmonics Measurements and
Instrumentation for Power Supply Systems and Equipment Connected to them,
 IEC 61000-4-15:2011 – Electromagnetic compatibility (EMC) – Testing and Measurement
Techniques - Flickermeter - Functional and Design Specifications,
 EN 50160:2010 – Voltage characteristics of electricity supplied by public distribution networks.
Safety standards:
 IEC 61010-1 – Safety requirements for electrical equipment for measurement control and
laboratory use. Part 1: General requirements
Standards for electromagnetic compatibility:

Aggregation of measure-
ments at different inter-
vals
IEC 61000-4-30 Class A:
 Basic measurement time for parameters (voltage, current, harmonics, unbal-
ance) is a 10-cycle interval for 50 Hz power supply system and 12-cycle inter-
val for 60 Hz system,
 Interval of 3 s (150 cycles for the nominal frequency of 50 Hz and 180 cycles
for 60 Hz),
 Interval of 10 minutes,
 Interval of 2 h (basing on 12 intervals of 10 min.)
 Synchronization of aggregation intervals
