Power Quality Logger

Using the 1745 Power Quality Logger

27

Signal Sampling

Input signals (up to three voltages and four currents) are filtered with an anti-
aliasing filter and digitized with a 16-bit A/D converter. The sampling rate is
10.24 kHz. All parameters are calculated from this data.

Resolution Accuracy

Resolution and accuracy depend on the logging parameter. For details see
“Technical Specifications”.

Voltage Variations

The interval value of the voltage is defined as the mean value of the RMS
values over the interval length defined in PQ Log.
