Carry out all measurement tasks with a single device.

PQI-D

The PQI-D power quality interface for low, medium and high-voltage networks is the central component of a system allowing all measurement tasks in electrical networks to be carried out. Our 19″ device is impressively flexible and can be both wall-mounted and installed in a control panel.

Record fault events quickly and easily

The PQI-D 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).

Available for wall assembly, control panel installation and as a 19″ plug-in unit

The PQI-D can come in various different sizes. It can be supplied as a 19″ plug-in card, with a wall-mounted housing, for insertion in a control panel or with a 19″ frame.

Record breaches of harmonic limits

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.
