TRANSFORMERS + SUBSTATIONS

Advanced power quality analysis tion. They also allow for users to minimise time spent in potentially hazardous envi- ronments and, by using a wireless con- nection to view data directly in the field, reduce the need to suit-up in personal pro- tection equipment. 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 intermit- tent events with detailed waveform data, helping to identify the root cause of distur- bances. For basic power quality logging, the Fluke 1746 captures all relevant power parameters for energy saving studies and electrical network planning and a full up- grade option to 1748 is available. For sim- ple 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 Power Quality Loggers, Energy Ana- lyze Plus, can calculate the limits of cur-

The Fluke range of Three-Phase Power Quality Loggers – 1742, 1746 and 1748 – available from Comtest, gives users fast, easy access to the data they need to make critical power quality and energy decisions in real-time. TheThree-Phase Power Quality Loggers are 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 simul- taneously 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 Energy Analyze Plus software quickly assesses the quality of power at the ser- vice entrance, substation, or at the load, according to national and international standards such as EN 50160 and IEEE 519. The devices feature an optimised user interface, flexible current probes and an intelligent measurement verification func-

rent harmonics based on installation pa- rameters to predict overload of the grid according to a wide range of international standards. This powerful predictive main- tenance feature enables current harmonics to be observed before distortion appears in the voltage, allowing users to prevent un- expected failures or non-compliance situa- tions and increase system uptime.
