The compact Power Quality Measuring Device
The Compact Power Quality Measurement Device
The PQI-DA is a power quality measurement device for low, medium and high-voltage networks that can be used as a power quality interface and as a measuring device to record all the defined qualities of AC networks. It is particularly suitable for monitoring special reference quality levels or characteristics agreed between an energy supplier and a customer.

Technical Data Sheets
Divisible differential current transformer
Record fault events quickly and easily
The PQI-DA records fault events at 96 μs sampling values and at a length (preceding and subsequent history of the event) that can be freely selected. Fault events are also recorded composed of the effective values of half period values (10 ms).
With a wall-mounted or DIN-rail housing
The housing can be mounted on a wall or profiled rails. This means the device can be flexibly deployed in many different applications.
Record limit breaches quickly and simply
When a limit (harmonic or voltage THD) is exceeded, the device records the spectrum of all harmonics from the 2nd to the 50th harmonic. The broad spectrum of harmonics recorded allows the user to carry out well-founded analysis.

The right interface for every application
Every component has two RS 232 interfaces (COM1 and COM2) and two interfaces each for the system and transport bus E-LAN. The PQI-DA can optionally be fitted with an integrated TCP/IP interface. In this case, COM 2 is removed.
The suitable Software offers the user more reasons, to use the PQI-DA
The WinPQ system solution for all built-in A. Eberle fault recorders, power quality monitoring devices and mobile network analyzers. Monitor power quality permanently – from the high-voltage grid to the end-user in a system. Intuitive operation despite the vast amount of data handled.
