One-touch advanced power quality analysis

August 2018 Electrical Power & Protection

Comtest has announced the availability of Fluke’s range of three-phase power quality loggers – 1742, 1746 and 1748 – giving users fast, easy access to the data they need to make critical power quality and energy decisions in real time.

Compact and rugged, these instruments are designed specifically for technicians and engineers who need the flexibility to troubleshoot and quantify energy usage, and analyse power distribution systems. Fully compliant with international power quality standards such as IEC 61000-4-30 and capable of simultaneously logging up to 500 parameters while also capturing events, the Fluke 1740 Series helps uncover intermittent and hard to find power quality issues easily. The included Energy Analyze plus software quickly assesses the quality of power at the service entrance, substation, or at the load, according to national and international standards like EN 50160 and IEEE 519.

An optimised user interface, flexible current probes, and an intelligent measurement verification function allows digital verification and correct connections make setup easier, considerably reducing measurement uncertainty. The devices also allow users to minimise time spent in potentially hazardous environments, while reducing the need to suit-up in PPE by using a wireless connection (WiFi) to view data directly in the field.

Measures all power quality and power parameters

The Fluke 1748 logs over 500 different parameters for each averaging period. This allows for the analysis of power quality in detail and the correlation of intermittent events with detailed waveform data, helping to identify the root cause of disturbances. For basic power quality logging, the Fluke 1746 captures all relevant power parameters for performing energy saving studies and electrical network planning with a full upgrade option to 1748 available. For simple load and energy studies the Fluke 1742 offers optimal performance in a rugged package and can be upgraded to 1746 or complete 1748 functionality.

Calculates current harmonics limits

When downloading data from the Fluke 1748 loggers, Energy Analyze Plus can calculate the limits of current harmonics based on installation parameters to predict overload of the grid according to a wide range of international standards. This powerful predictive maintenance feature enables current harmonics to be observed before distortion appears in the voltage allowing users to prevent unexpected failures or non-compliance situations and increase system uptime.

Easy to use

Fluke power quality loggers are designed with the technician in mind. The four current probes are each connected separately allowing flexibility and simplicity, the instrument automatically detects, scales and powers the probes so users do not have to worry about ensuring the measurements are correct.

Capturing logged data is just one part of the task, users then need to create useful information and reports that can be easily shared and understood by their organisation. Fluke Energy Analyze plus software makes that task as simple as possible. With powerful analysis tools and the ability to create customised reports in minutes users can communicate findings and solve problems to optimise system reliability and show savings. A range of built-in report templates for industry standards such as EN 50160, IEEE 519 and GOST enable one-click reporting to create high quality reports at the touch of a button.

Reports can be modified as standards evolve, or new versions become available.

The 1740 series products are built to withstand tough working environments. The flexible current probes are IP65 rated and suitable for most installation situations; the optional IP65 voltage adaptor ensures safe, reliable operation even in harsh conditions. Standard 2 m leads simplify connection on difficult to access conductors, and optional 5 m leads are useful when installing in difficult locations. With the capability of powering the instruments from the power line up to 500 V, installation is simple.
