New 3-phase power loggers

December 2015 Electrical Power & Protection

Fluke has launched two new three-phase power loggers, the 1736 and 1738, which give users the data needed to make critical power quality and energy decisions in real time. They are specifically engineered to conduct energy studies and basic power quality logging, automatically capturing and logging over 500 power quality parameters for more insight into the data needed to optimise system reliability and savings. They are the first three-phase power loggers built with the Fluke Connect mobile app and software, enabling users to measure, capture and log all relevant characteristics of electric power and allowing them to access and analyse large data sets.

The 1736 and 1738 have greater visibility, reduced uncertainty and better decision-making capabilities. They can automatically capture and log over 500 power quality parameters. Visibility through Fluke Connect enables users to view collected data to ensure it is correct, either at the panel or remotely. Measurement system errors are significantly reduced by powering the logger directly from the measured line and utilising the intelligent verification function that digitally corrects common connection issues. Data can be accessed and shared remotely via the Fluke Connect app to maintain safer working distances and make critical decisions in real time, reducing the need for protective equipment, site visits and check-ins. Chart and graph measurements create detailed reports with Fluke Energy Analyse Plus software.

The power loggers also have more power quality measurement capability than their predecessor, the Fluke 1730, a pure energy logger. This functionality is a subset of the Fluke 1736/1738. For users performing both basic power quality studies and energy studies, the 1736/1738 enables measurement, capture and logging of all relevant characteristics of electric power and gives access to management and analysis of large data sets. The 1738 includes advanced limit based analysis using EN510160 limits, the capability to connect two Fluke Connect devices for logging of supplementary parameters and a WiFi/Bluetooth (BLE) dongle.

Features of the 1736 and 1738 include:

• Simultaneous logging of key measurements such as log voltage, current, power, harmonics and associated values.

• Measurement of all three phases and neutral with the four flexible current probes included.

• Connectivity on a portable power logger, with data viewed locally on the instrument via the Fluke Connect app or through the facility’s Wi-Fi infrastructure.

• Comprehensive logging, with the ability to store 20+ separate logging sessions on the instruments, and all measured values being automatically logged for measurement trends.

• Capture of dips and swells, including event waveform snapshot, date, timestamp and severity, to help pinpoint potential root causes of power quality issues.

• Complete in-the-field setup through the front panel or Fluke Connect app.

• Convenient instrument powering from the measured circuit, eliminating the need to find a power outlet while allowing the instrument to be secured safely inside electrical panels.

• Fully integrated logging, with other Fluke Connect devices being connected to the Fluke 1738 to simultaneously log up to two other parameters.

• Two USB ports, one for PC connection and the other for quick, simple data download to standard USB thumb drives or other USB devices for in-place, undisrupted logging.

• Compact size.

• The highest safety rating in the industry – 600 V CAT IV/1000 V CAT III.

• Security from theft with an optional durable Kensington lock.

• The ability to download and analyse every detail of energy consumption and power quality with automated reporting using Power Quality Analyse application software.

Accessories for the 1736, the hanger kit and magnetic voltage probes, make installation much easier. Additionally, the upgrade kit allows users to fully upgrade the 1736 to a 1738 with all the functionality and accessories included with 1738. The auxiliary input cable is very useful if users wish to log other parameters like temperature along with energy. If there is a wide variety of circuit types and sizes, additional current probes are very useful. If users are planning to integrate their measurements fully they can also buy FC3000 modules which can connect to the 1738 and log those measured values.
