If the Fluke 1748/INTL Three-Phase Power Quality Logger identifies an incorrect connection it will alter it digitally without the user having to remove connected test leads or clamps.

Further to this, the Fluke 1748/INTL Three-Phase Power Quality Logger automatically detects, scales and powers connected clamps and/ or probes thereby ensuring that the instruments can be depended upon to acquire accurate, reliable and relevant data. Up to four current probes can be connected separately, allowing the user to tailor the Fluke 1748/INTL Three-Phase Power Quality Logger to the application and ensuring maximum flexibility.

Finally, the Fluke 1748/INTL Three-Phase Power Quality Logger is equipped with a quick, guided and graphical PC-application setup that enables the user to configure the instrument so that it is able to gather the relevant data correctly, accurately and reliably.

Accessories

As mentioned above, up to four flexible current probes (NOT supplied in the Fluke 1748/B/INTL kit) can be connected to the Fluke 1748/INTL Three-Phase Power Quality Logger. These thin, IP65, flexible probes can be used to inspect most installations and allow the user to access tight spaces and difficult-to-reach conductors and systems. Their wide ranges (probe dependent) ensure high accuracy for each application.

Additionally, the Fluke 1748/INTL Three-Phase Power Quality Logger is supplied with 2m test leads allowing the user to access difficult-to-reach conductors.

When data is downloaded to the user’s PC, and subsequently the Fluke Energy Analyse Plus Software, the program will automatically calculate the limits of the current harmonics using the installation parameters and thereby predict grid overload in accordance with a variety of international standards. Using this data, the engineer/ technician can monitor harmonics before distortion appears in the voltage enabling him/her to increase the system’s uptime by preventing unexpected failures and non-compliance situations.

Data imported to Fluke’s Energy Analyse Plus Software may be exported in PQDIF and NeQual formats for use with third-party software. The operator is also to select a particular parameter to create a customised view of logged measurements for advanced data correlation. He/she can view hour/hour, day/day and week/week comparisons. Using this software the engineer or technician is able to analyse every detail of the energy consumption and power quality state-of-health.

Finally, at the touch of a button, the user is able to create EN 50160, IEEE 519, GOST 33073 reports. The templates of these reports can be altered as necessary in order to accommodate evolving standards.
