Data analysis and reporting
Osprey Lite is supplied free of charge and continuously updated.
Download from www.ctlab.com.
It generates both NRS 048 and EN 50160 PQ reports.
It allows basic and advanced analysis of PQ waveform events and
trends.
Data can be exported to in .csv and PQDIF format for additional analysis
in third party software packages.
Data downloading can be automated by configuration of the Impedo DUO with
Osprey Lite.
All measurable PQ parameters can be recordable
simultaneously.

Impedo DUO External Interfaces
2.3.2.1
Voltages
The two 3-phase voltage inputs to the Impedo DUO interfaces directly to 110 V VT
circuits or directly to mains connections, which has to be less than 600 V line-to-
neutral.
Voltage measurements are differential.
6 voltage input terminals are used for each meter.
Input channel 1-3 is referenced to a neutral (4th terminal) connection. This
4th terminal acts as a reference channel and can be connected to any phase
voltage or neutral point if a 3-phase line-line voltage circuit is measured.
If it is a 3-phase line-neutral voltage circuit, then the 4th terminal will be
connected to the neutral voltage.
The 5th and 6th terminal is the 4th differential channel.
