Comtest is offering Fluke’s range of three-phase power quality loggers – model numbers 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, they are designed specifically for technicians and engineers who need the flexibility to troubleshoot, 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 allow for digital verification and correct connections to 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 personal protective equipment by using a wireless connection (Wi-Fi) to view data directly in the field.
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.
When downloading data from the 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.
The loggers’ four current probes are each connected separately, allowing flexibility and simplicity, and the instrument automatically detects, scales and powers the probes so users don’t have to worry about ensuring the measurements are correct.
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 adapter ensures safe, reliable operation even in harsh conditions. Standard 2 m leads simplify connection on difficult to access conductors, and optional 5m 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.
The power quality loggers include simple but effective accessories like the MA-C8 adapter, making powering the instrument with a line cord easy when not in the field. Ports that aren’t always needed in the field are IP65 protected, including the Ethernet, USB, AUX and I/O ports, protecting for both moisture and dirt ingress. The status LEDs give a clear indication of what the instrument is doing without having to touch any controls.
