Fluke 1760TR Three-Phase Power Quality Recorder Topas

Product Details:

The Fluke 1760 series consists of four different variations of the same tester. This version, the standard kit TR model, comes with the ability to capture and analyse fast transients and ships with current/voltage probes (not included in the basic kit).

Designed for attachment to three-phase systems, the 1760 is an extremely versatile power quality instrument that constantly evaluates and logs power quality measurements over an extended period of time. The system is fully compliant with IEC 61000-4-30 Class-A standards and ensures that all measurements are carried out with high accuracy, giving the user the ability to diagnose a wide range of power quality problems and issues.

The recorder can be used to capture total harmonic distortion, voltage and current harmonics (including interharmonics), frequency, unbalance, flicker, kWh, power factor, power (P, Q and S), current and voltage with continuous readings. It also includes the ability to capture voltage events (dips, swells and interruptions and includes triggered recordings, online mode and can perform fast transient analysis up to 10MHz.

Up to 8 different inputs can be connected to the 1760 simultaneously (up to 8x voltage or 4x voltage and 4 x current) using the included probe sets. The internal memory of the tester constantly logs a significant amount of data directly from these inputs and this information can then be downloaded to PC afterwards to ensure that further analysis of the system under test can take place.

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
 Free Interval, e.g.: 15 min, 2h
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.
