2 Introduction
ibaPQU-S is a modular system to measure power qualitypower parameters using
ibaPQU-S as central unit.
ibaPQU-S measures raw values such as current and voltage in sync with the grid and
calculates the characteristic values according to IEC 61000-4-30 Ed. 3 Class A. Charac-
teristic values include:
Frequency
RMS and maximum value, rectified value, form factor, crest factor
FFT (harmonics, interharmonics up to 50th order)
THD (Total Harmonic Distortion)
Phase values (U/I phase angle to the reference voltage)
Power values (active power, apparent power, reactive power, cos θ, electric energy,
power factor for individual lines and for the total grid)
Symmetrical components (positive, negative and zero sequence component) and
supply voltage unbalance
Flicker (according to IEC 61000-4-15, short-term, long-term)
Event detection (voltage dip, voltage swell, voltage interruption, rapid voltage
changes, ripple control signal)
In addition, ibaPQU-S calculated the following values:
Commutation notches
Flicker for currents
Symmetrical components (positive, negative and zero sequence component) and
current unbalance
ibaPQU-S is suitable for the following grids:
DC
50 Hz
60 Hz
