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.

2.2 Measurements according to EN50160
The DIN EN 50160 standard specifies the voltage quality in public supply grids. It defines
features and characteristic values for the supply voltage quality and limit values. The
optional “EN50160” mode in ibaPDA captures all characteristic voltage values defined in
the standard. Beyond the requirements of DIN EN 50160, currents can optionally be
configured for evaluation.
The ibaAnalyzer software is used for measurement evaluation and generation of reports.
Moreover, it is possible to create long-term trending and clearly structured reports that
can be used e.g. to prove compliance with the DIN EN 50160 standard.

Important note
Unlike other iba devices that support the 32Mbit Flex protocol, it is allowed to operate
only two ibaPQU-S systems in cascade configuration at one free 32Mbit Flex link of an
ibaFOB card because of the high sampling rate of 10 - 40 kHz and the high data volume
in the network channel of the Flex protocol.
Important note
When starting up the device for the first time, check the status signals of ibaPQU-S
(data loss etc.). If multiple signals occur, the time base of the system has to be ex-
tended.

7.5.2 Debounce filter
There are four debouncefilters for each digital input.They can be chosen and configured
independently of each other for each signal. The following filters are available:
“Off” (no filter)
“Stretch rising edge”
“Stretch falling edge”
“Stretch both edges”
“Delay both edges”
For each filter, a debounce time ranging between [1µs…65535µs] has to be defined in
µs.
“Off”
The measured input signal is forwarded directly without filtering.
“Stretch rising edge”
The first rising edge sets the output signal (red) to logical 1 and it remains logical 1 for
the set debounce time. Subsequently, the channel is transparent again and waits for the
next rising edge.
Figure 5: Debounce filter: “Stretch rising edge”
“Stretch falling edge”
The first falling edge sets the output signal (green) to logical 0 and it remains logical 0
for the set debounce time. Subsequently, the channel is transparent again and waits for
the next falling edge.
