Applications

Detailed disturbance analysis — Perform high-

speed transient analysis and uncover the 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. With 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.

Simultaneous measurement of independent power systems — Built with Galvanic separation

and dc coupling of voltage inputs, the instrument can conduct complete measurements on dissimilar power systems. For example, the Fluke 1760 can troubleshoot UPS systems by simultaneously record ing 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.

What is Class-A conformity?

Power quality measurement is a relatively new, and quickly evolving field. There are hundreds of manufacturers around the world with unique measurement methodologies. Whereas basic single- and three-phase electrical measurements, like rms volt age and current were defined long ago, many power quality parameters were not previously defined, forcing manufactur ers to develop their own algorithms. With so much variation between instruments, electricians tend to waste too much time trying to under-stand an instrument’s capabilities and measure ment algorithms instead of understanding the quality of the power itself!

The new IEC 61000-4-30 Class-A standard takes the guess work out of selecting a power quality instrument. The standard IEC 61000-4-30 deﬁnes the measurement methods for each parameter to obtain reliable, repeatable, and comparable re sults. In addition, the accuracy, bandwidth, and minimum set of parameters are all clearly deﬁned.

Fully Class-A compliant

The Fluke 1760 is fully compliant with the new IEC 61000-4-30 Class-A standard, which defines the measurement methods required for each power parameter in order to obtain reliable, repeatable, and comparable results. With the GPS time synchronization accessory, data recorded with multiple instruments can be correlated with Class-A precision.

Individual trigger settings provide flexibility when capturing events, rms values, waveforms, and fast transients. The instrument runs with default settings, so that the user does not need to set triggers in standard applications. Individual settings can be stored for next time.

User-configurable operation

The versatile measurement algorithms and trigger settings allow the expert and general users to opti

mize the Fluke 1760 for each application in order to capture exactly the data required. Data can be transferred to a computer directly, or via an Ethernet network and can be retrieved during recording without interrupting the measurements.

Rugged and reliable

The instrument, accessories, and power supply help you safely conduct tests with a 600 V CAT IV rating per EN 61010-1 conformity requirements. The Fluke 1760 features a double insulated enclosure, which helps protect the user, equipment, and surroundings from electrical shock. With a 2 GB compact flash memory instead of a hard disk, there are no rotating parts inside the instrument, increasing its reliability and durability for everyday use.

Broad measurement range

Developed in cooperation with power utilities, the EN50160 statistical analysis presents a summary of the quality of voltage against internationally defined limits. When a threshold is exceeded, the Fluke 1760 automatically captures voltage and cur rent waveform data on all phases simultaneously. Nearly every power quality and power parameter is measured, including rms values, flicker, voltage dips, voltage swells, voltage unbalance, current and voltage harmonics to the 50th, interharmonics, THD, mains signaling, reactive power, transients, and power factor.

Configurable settings for EN50160 statistical overview and DISDIP summary curve enable the user to define custom limits and settings for specific applications and local standards.

Plug and play

The Fluke 1760 Power Quality Recorder features easy plug and play setup for immediate use. The current and voltage probes are plugged in sepa rately to the instrument, which automatically detects, configures, and provides power to the probes. All accessories are individually calibrated and can be shared with multiple Fluke 1760 recorders.

The event list summarizes how often an event occurred during the selected time period.

By double-clicking on an event, the software displays any trends and waveforms related to this event.

PQ Analyze Software

The Fluke 1760 includes comprehensive software for detailed power quality analy sis on Windows

based PCs. In the online mode, the software enables remote instrument setup, job processing, real-time veri fication of actual measurement values, and data download. Data can be viewed in trend diagrams for root cause analysis or in a variety of statistical summaries. You can also generate profes sional reports with the Report Writer function.

The 1760 provides flagging of data according to IEC 61000-4-30 Class-A. The flagging feature alerts the user that a dip, swell, or interruption occurred during a specific time interval. Values out of nominal ranges are marked by either a colored background or with a flag symbol.

The report-generator function allows the user to create custom professional reports quickly and easily. The PQ Analyze Software features templates for standard reports.

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.

The Fluke 1760 logs rms values, together with corresponding minimum and maximum values, continuously – with the following time aggregations:

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

16-bit A/D converter. All channels are sampled synchronously with a common quartzcontrolled clock pulse.

The ﬁlters achieve extremely high accuracy throughout a wide frequency range. 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. This is also valid under extreme operating conditions such as transient voltages at the output of converters.
