5 Fluke Corporation Fluke 1760 Three-Phase Power Quality Recorder Topas
Overview of measurement functions
Statistical
evaluation
Power quality statistics according to EN50160 and DISDIP tables
like ITIC, CEBEMA, ANSI EN 50160
Event list Dips, swells, and interruptions are detected and stored in the
event list. Also any trigger which fires generates an event,
which is added to this list. Together with the event, rms values,
transients, and fast transients can be stored.
The event list shows the exact time of occurrence, as well as
duration and magnitude. Several parameters of the events can
be sorted. The user can thereafter select an event for further root
cause analysis.

Continuous
recording The Fluke 1760 logs rms values, together with corresponding
minimum and maximum values, continuously – with the
following time aggregations:
1 Day
10 min
Free interval, e.g. 15 min, h
Voltage
Current
Power P, Q, S
Power Factor
kWh
Flicker
Unbalance
Frequency
Harmonics/Interharmonics
Triggered
recordings
RMS with adjustable aggregation time between 10 ms
(1/2 cycle), 20ms (1 cycle), 200 ms (10/12 cycles) or 3 sec
(150/180 cycles).
Calculating rms values, harmonics, and interharmonics is
performed synchronous to the power frequency.
Basic aggregation for harmonics and interharmonics is 200 ms
Oscilloscope: Sample rate is 10.24 kHz for all 8 channels
Fast Transients: Sample rate is selectable from 100 kHz to
10 MHz for channel 1-4
