Measurement of Voltage Dips(Sags)/Swells

1 Cycle RMS Measurement with Half-cycle Sliding Window

Accura 2300S measures the RMS voltage over 1 cycle using a half-cycle sliding window. The time

resolution for the RMS value measured over 1 cycle is one half cycle. Dips(Sags)/Swells are detected

based on the RMS value measured over 1 cycle.

Dip(Sag)/Swell Detection

As it is defined in IEC 61000-4-30, voltage dips(sags)/swells are detected by measuring 1-cycle RMS

values refreshed each half cycle. The time resolution for dip(sag)/swell detection is one half cycle.
