2 Introduction
ibaPQU-S is a modular system to measure power quality 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 Distorsion)
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 cutoff, rapid voltage changes,
mains signalling voltage)
In addition, ibaPQU-S calculated the following values:
Commutation notches
Flicker for currents
Symmetrical components (positive, negative and zero sequence component) and
supply voltage unbalance
ibaPQU-S is suitable for the following grids:
DC
50 Hz
60 Hz
user-defined grids ranging between 10 Hz and 80 Hz frequency

2.1 Modular concept
The modular concept of the ibaPQU-S system is based on a backplane capable of ac-
commodating the central unit plus up to 4 input/output modules (I/O). ibaPQU-S operates
as a central unit with integratedmeasurement and calculation algorithms and additionally
features 8 digital inputs. The central unit can be expanded by up to 4 current and voltage
measurement modules.
The following I/O modules support the measurement and calculation of power quality
parameters:
Voltage measurement modules
ibaMS4xAI-380VAC (4 analog inputs for 380 VAC)
ibaMS8xAI-110VAC (8 analog inputs for 110 V AC)
ibaMS16xAI-24V (16 analog inputs for ±24 V)
ibaMS16xAI-24V-HI (16 analog inputs for ±24 V, high impedance)
ibaMS16xAI-10V (16 analog inputs for ±10 V)
ibaMS16xAI-10V-HI (16 analog inputs for ±10 V, high impedance)
Current measurement modules
ibaMS3xAI-1/100A (3 analog inputs for 1 AAC/100 A DC)
ibaMS3xAI-5A (3 analog inputs for 5 AAC)
ibaMS3xAI-1A (3 analog inputs for 1 AAC)
ibaMS16xAI-20mA (16 analog inputs for ±20 mA)
Combination module
ibaMS4xADIO (combination module with 4 analog inputs/outputs and 4 digital in-
puts/outputs respectively; the 4 analog inputs are supported for the ibaPQU-S func-
tion, voltage or current measurement configurable)
All other I/O modules of the iba modular system are equally supported; however the
signals are transmitted as raw values only.
The raw signals and internally calculated characteristic values are sent to the ibaPDA
data acquisition system via a bidirectional fiber optic connection for visualization and
recording. Signal configuration and characteristic value selection are performed in
ibaPDA. Additionally, ibaPDA allows advanced calculations, configuring event-based
measurements based on triggers or displaying faults using an alarm function.
