Fluke 1760 Three-Phase Power Quality Recorder Topas
This power logger is fully compliant with IEC 61000-4-30 Class-A and is used for extremely detailed, constant evaluation of power quality and compliance testing.
The Fluke 1760 features 8 separate ports, allowing it to receive inputs from 4 current, 4 voltage or 8 voltage channels simultaneously for a comprehensive view of power quality. Detected values are automatically logged directly onto the recorded, ensuring that the user can read them back and analyse captured readings further by using the included software package. With 2GB of memory included as standard, the 1760 can log a significant amount of data over a time period.
Once connected to a system this power recorder can be used to measure all power quality statistic as defined by EN50160. This allows the tester to measure voltage events (including dips, swells and interruptions) plus continuous recording of voltage, current, power (P, Q and S), power factor, kWh, flicker, unbalance, frequency, voltage and current harmonics to the 50th, interharmonics, total harmonic distortion, mains signalling, triggered recordings and includes an online mode for oscilloscope, transients and events.

Overview of Measurement Functions
Statistical Evaluation
Power quality statistics according to EN50160 and DISDIP tables like ITIC, CEBEMA, ANSI
Event List
Dips, swells and interruptions are detected and stored in the event list. Also any trigger which fires generates an event added to this list.
The Event list shows the exact time when the event occurred as well as the duration and magnitude. Sorting by several attributes of these events is possible to select one for further root cause analysis.
RMS values, transients and fast transients can be stored if a trigger fires.
Continuous Recording
Fluke 1760 records rms values together with corresponding minimum and maximum values for:
• Voltage
• Current
• Power P, Q, S
• Power Factor
• kWh
• Flicker
• Unbalance
• Frequency
• Harmonics/Interharmonics
continuously with the following time aggregations:
Day
10 min

Triggered Recordings
rms:
Aggregation time is adjustable between 10 ms (1/2 cycle), 20ms (1 cycle), 200ms (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 200ms
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 FFT of Fast Transients
Mains Signalling
Phases and N-conductor, Voltage and current
Online Mode
Variable refresh rate. This feature allows verification of instrument set up and delivers a quick overview of oscilloscope, transients and events.

Input filter
Each channel is equipped with a passive low-pass filter, an anti-aliasing filter and a 16-bit A/D converter. All channels are sampled synchronously with a common quartz-controlled clock pulse.
The filters protect against voltage transients and limit the signal rise rate, reduce high frequency components and especially the noise voltage above half the sampling rate of the A/D converter by 80 dB, thus achieving very small measuring errors in an exceptionally large amplitude range. This is also valid under extreme operating conditions like transient voltages at the output of converters.
