Fluke 41B Power Meter

 41B
The Fluke 41B Harmonics Analyzer combines the ease of use of a digital multimeter, the visual feedback of an oscilloscope and the power of a harmonics analyzer in a single instrument. If you're testing power on three-phase systems or trouble-shooting harmonics on non-linear loads, no test tool makes it easier.

The Model 41B is ideal for further analyzing data and optimizing system performance. Use the Fluke 41B's FlukeView® software (included) to download acquired data to a printer or an MS-DOS® or Windows® compatible computer for analysis and presentation.

Features at a Glance

Three Views of each reading

  • Waveform
  • Bargraph showing harmonic levels
  • Numeric values

Real-time Display Updates

Display updates three times a second for a dynamic view of actual circuit conditions.

Comprehensive Measurements

Measure rms, peak and total harmonic distortion (THD) for complex voltages and currents - with no manual calculations required.

Three-Phase readings

From a simple single-phase measurement, automatically calculates three-phase power for 3-wire balanced loads (typically 5% or less imbalance). To make the single-phase measurement, simply connect the meter as shown and select the 3º, 3C watts display.

System Critical Data

Immediate readings of Power Factors, KVAR, Crest Factor, K-Factor.

Display Harmonics individually to the 31st

Min/Max and Average Recording

Data Storage

Up to eight complete measurement sets.

Isolated Serial Interface

Communications with a serial printer or DOS® or Windows®-compatible computer.

Safety Designed

To meet the latest standards: IEC 1010-1, pollution degree 2, Installation Category III, material group II, 600 V. Double insulated protection as described in IEC 1010-1, Annex H.

Volts

Display

One cycle of the fundamental waveform and its frequency. Instantaneous voltage at cursor position.

figure 2

Application

Identifying sources of harmonic currents. Obtaining data for designing, specifying or sizing transformers, filters, etc.

Amperes

Display

%-fundamental or %-rms, rms value, frequency, and phase angle of fundamental or harmonic currents (up to 31st), as selected by cursor from bar graph.

Application

Identifying sources of harmonic currents. Obtaining data for designing, specifying or sizing transformers, filters, etc.

Watts

Display

Watts, volt-amps, power factor (total) and displacement power factor of fundamental of single-phase or three-phase power.

Application

Identifying displacement versus total power-factor. Determining proper power-factor correction methods.
