Fluke Corporation has introduced more accurate electrical power standards designed to deliver stable, precise reference power and energy for use in calibrating electrical measurement equipment.

Fluke said that its 6105A and 6100B Electrical Power Standards provide the stability and accuracy required by users including national measurement institutes, instrument service and calibration firms, electronics manufacturers, power utilities and standards laboratories.

Deregulation and the increasingly distributed nature of today’s power supply network mean that measurements must be made more frequently, with a higher degree of accuracy.

Global moves to smart metering and smart grid technology require better measures of electricity.

As accuracy specifications get tighter, measurement techniques become more important.

The Fluke 6100B Power Standard is said to meet the accuracy requirements for today’s power quality testing standards.

In addition, it features improved accuracy and increased voltage channel current drive, for calibrating energy meters that take power from their voltage input.

The Fluke 6105A provides all the functionality of the 6100B, with even better accuracy to match that of the best measurement devices for sinusoidal waveforms.

The 6105A Electrical Power Standard is specifically designed to provide the accuracy required to verify the performance of secondary standards such as the Radian Research RD and RM range, the Zera EPZ303 and COM 3003; also the MTE (EMH) K2006, Calport 300, SRS PRS PWS and PTS series products.

Few systems can match the 0.007 per cent (66ppm) one-year energy accuracy provided by the 6105A for sinusoidal waveforms.

Waveforms with high harmonic distortion are also delivered with similar accuracy traceable to national and international standards.

Choosing between a 6100B or 6105A depends on the user’s accuracy requirements.

Both models meet all accuracy requirements of power quality testing to the IEC 61000-4 series of standards.

The 6100B can also be used to type test 0.1 per cent to two per cent energy meters, while the 6505A has a very high accuracy for calibrating and type testing secondary standard energy meters and watt-hour meters.

To maintain the highest accuracy for all specifications, the 6105A should be fully characterised and calibrated annually.

To reduce the cost of ownership, a calibration adjustment regimen can maintain traceability for one-, two-, three-, or four-phase systems using a single-phase power/energy meter with accuracy determined by the meter used.

This regimen can be applied to 6100B or 6105A masters and their auxiliary counterparts.

A Microsoft Windows user interface can be used to operate the 6100B and 6105A.

The interface can be accessed through a combination of front panel knobs and buttons, or by connecting the user’s mouse and keyboard.

Actions are then viewed on the high-resolution 8in TFT display.

Status information of all four phases is displayed, alongside more detailed information on current parameters being set or adjusted.

In addition, the 6100B and 6105A can be operated under remote control.

Where multi-phase systems are operated, control of the auxiliary devices is via the master unit.

The 6100B and 6105A conform to the IEEE 488.1 standard and supplemental standard IEEE 488.2.

The programming language complies with the Standard Commands for Programmable Instruments (SCPI).

Complex instrument setups can be saved and recalled within the instrument or saved and recalled from a USB storage device.

Fluke Calibration

Fluke Corporation was founded in 1948, specialising in electrical test and measurement products. Early in its history, Fluke recognised that the very best electrical metrology would be needed to support its products and undertook to develop this capability. From this activity, the calibration business was born. Over the years, many breakthrough calibration products were introduced, establishing Fluke as a leader in electrical metrology.

In 2000, Fluke acquired Wavetek Precision Measurement. In 2001, Fluke’s calibration business expanded into the temperature field with the acquisition of Hart Scientific and then into pressure and gas flow with the acquisition of DH Instruments (2007), followed by Ruska and Pressurements (2010).

The unified business’s unmatched breadth and depth in metrology puts Fluke Calibration in a unique position to deliver today’s and tomorrow’s calibrations solutions to customers who demand the very best, supported by an organisation they can count on for the long term.
