 Fluke 1760

Class-A compliance for the most demanding power quality tests

The Fluke 1760 Three-Phase Power Quality Recorder is fully compliant to IEC 61000-4-30 Class-A, for advanced power quality analysis and consistent compliance testing. Designed for analysis of utility and industrial power distribution systems, in medium- and low-voltage networks, this power quality monitor provides the flexibility to customize thresholds, algorithms, and measurement selections. The 1760 power recorder captures the most comprehensive details on user-selected parameters.

Applications

Detailed disturbance analysis – Perform high-speed transient analysis and uncover root cause of equipment malfunction for later mitigation and predictive maintenance. The fast transient option, with its 6000 V measurement range, allows capture of very short impulses such as lightning strikes.

Class-A quality-of-service compliance – Validate incoming power quality at the service entrance. Thanks to Class A compliance, the Fluke 1760 allows undisputable verification.

Event correlation at multiple locations – Utilizing GPS time synchronization, users can quickly detect where a fault occurred first, either inside or outside the facility.

Galvanic separation and DC coupling – Allows complete measurements on dissimilar power systems. For example troubleshoot UPS systems by simultaneously recording the battery voltage and power output.

Power quality and power load studies – Assess baseline power quality to validate compatibility with critical systems before installation and verify electrical system capacity before adding loads.

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:

 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.
