PQI-DA smart Description
The new Power Quality Analyser and sequence of events recorder PQI-DA smart for low,
medium-voltage grids is the central component of a system with which all measurement
tasks in electrical grids can be solved. The PQI-DA smart can be used as either a Power
Quality Interface in accordance with grid quality standards or as a measuring device for all
physically defined variables in three-phase grids.
In addition to standard evaluations, the PQI-DA smart also features a high speed sequence
of events recorder with a recording rate of 40.96kHz/10.24kHz as well as an 10ms RMS recorder. This enables a detailed evaluation of faults in the grid.
In particular, the component is suitable for monitoring, registering, evaluating and recording special reference quantities or quality agreements between the energy supplier and the
customer
Modern Power Quality measuring devices operate in accordance with the IEC 61000-4-30
(2008) standard. This standard defines measurement methods in order to create a comparable basis for the user.
Devices from different manufacturers that operate according to this standard must give the
same results.
The standard distinguishes two classes of measuring devices:
0 Class A devices are used mainly for measurements relating to contracts in customersupplier relationships.
0 Class S devices can be used to determine statistical quality values.

Mechanical design
The PQI-DA smart can be wall-mounted (optional DIN-rail), in-panel mounted (optional mounting frame) or used as a DIN-rail housing. All connections are accessible via Phoenix type
terminals. The connections are made by using plug-in/clamping technology, except for the current and voltage inputs.
For the TCP/IP interface one RJ 45-connector is available.

Connecting PQI-DA smart Power IN in a 3-wire grid
If in a 3-wire grid power is connected to the IN input, it will be calculated and recorded.
The values measured for IN are not included in the 3~ power calculations. It is, therefore, possible to use the PQI-DA smart to capture any additional current via the fourth power input.

than one gigabyte, the time period of the SD-card is much longer than into the PQI-DA smart.
Confirm with “OK” and the PQI-DA smart will start automatically to copy the selected internal
memory onto the SD card.
The minimum size of an external memory card is one gigabyte. The device can manage
memory cards up to a max. of 32gBytes.

Technical Data
In the display menu “memory” the progress of the copy process is shown.
 To remove the memory card, operate the "Remove SD card“ function.
The "Remove SD card“ function stops the copying function for the measuring data of the
internal memory to the SD memory card and releases the card for removal.
1 Memory allocation
The memory allocation of the PQI-DA smart uses the internal 1 gigabyte memory in a circular
ring buffer for all measurement data.
The ring buffer is allocated as follows:
0 512 MB circular buffer for long-term measurement data
0 416 MB circular buffer for sequence of events recordings (oscilloscope images; ½ period
RMS values)
0 16 MB circular buffer for log files and Power Quality events

WinPQ smart software
The free WinPQ smart evaluation software has been created exclusively for the Network Analyser PQI-DA smart and includes the following functions:
0 Parameterisation of the Network Analyser PQI-DA smart
0 Online analysis of the measurement data
0 Reading the measurement data from the measuring device
0 Evaluating measurement data
0 Firmware update for PQI-DA smart
The powerful database and evaluation software WinPQ which is available at an extra charge
supports all mobile and permanently installed Network Analysers supplied by A. Eberle in one
system. Measuring data from different devices can be compared to each other. There is a fully
automated and permanent connection to all permanently installed devices. Detailed PowerQuality reports and sequence of events recording are automatically created by the system and
can be sent via e-mail. There are separate operating and commissioning instructions for the
WinPQ software.
6.1
Installing the evaluation software
To start the installation of the evaluation software, place the installation CD in your CD-ROM
drive. If the Autostart function is activated, the installation program starts automatically. Otherwise, go to the root directory of your CD-ROM drive and start the program by doublecLicking the file
.
The installation complies with the Windows standard, including uninstalling the program system via the "Software" option on the Control Panel. The installation location of the program
(target directory) can be freely selected during installation.
Install the software in a directory in which you also have read and write rights.
The start icon
Page 52
is created automatically on your PC's Desktop.
WinPQ smart software
Uninstalling the software via the control panel
The components are removed from the PC using Windows "Control panel“.
Under "Software“, "WinPQ smart“ entry, use the "Remove" button to delete the evaluation software.
All parts of the program, including the generated links, are completely removed after a single
confirmation. Before uninstalling the program, the components launched must be closed.
Software Update
You can find the evaluation software and all updates and the current device firmware, free of
charge, on our website under the product group "Power Quality / Software WinPQ smart":
www.a-eberle.de
Please also install the current device firmware on your measuring device to ensure that you
can use any new functions.

As the EN50160 only specifies limits for harmonics up to the 25th ordinal, the compatibility
level of IEC61000-2-2 has been stored for the 26th to the 50th harmonics in the basic settings.
Compatibility levels in accordance with EN50160 & IEC61000-2-2 are shown as green limit value bars.

0 Interharmonic voltages conductor-earth
0 Interharmonic currents
If an interharmonic is selected with the mouse pointer, this measurement value is displayed in
the field on the top right.
1 Explanation of the grouping process in accordance with the IEC:
To evaluate the interharmonics in the grid, subgroups are created. In each case, all of the
interharmonics between two harmonics are combined into one harmonics subgroup.
Example for 50Hz: Interharmonic H2 includes all frequencies from 110Hz to 140Hz.

The centre frequency of the corresponding frequency band is stated.
Example: All frequencies from 8,805Hz to 9,000 Hz are located in the 8.9 kHz band.

K Factor
The values of the K-factors for phase currents are calculated from the corresponding RMS values Cn of the harmonics n = 1..40.
The K factor is a measure that indicates the ability of a transformer to withstand the current
harmonics of a system.
Various transformer suppliers offer transformers with, for example, K factors K=4, K=13, K=20

Transformers are heated more by harmonic currents than 50 Hz currents.
A transformer with a higher K-factor withstands this better and is not heated as much as a
transformer with a lower K factor.
The device shows the K factor for the current. Only the K values that appear at maximum power are of interest. Just as with the THD of the currents in %, the value is not relevant at very
low currents.

Harmonics / Interharmonics
The determination of the harmonics and interharmonics interval values displayed using the
methods of the IEC61000-4-30 Class A standard based on 10/12 period values.
The PQI-DA smart recognizes for all voltage and current channels, respectively, the harmonics
up to the 50th ordinal. To evaluate the interharmonics, harmonic subgroups are created. 50
subgroups are recorded for all current and voltage channels.

Frequency analysis 2 kHz to 9 kHz
In the frequency analysis 2 kHz to 9 kHz respectively 200 Hz frequency bands are summarized.
The specification of each frequency is the center frequency in this 200 Hz band.
Example: Frequency band 8.9 kHz corresponds to all 5 Hz spectral lines from 8.805Hz to
9.000Hz

For the EN50160 (events) only the voltage unbalance uu is relevant and corresponds to the ratio of the negative sequence to the positive sequence. The value is expressed in [%].
