Power quality measurement is a relatively new, and quickly evolving field. There are hundreds of manufacturers around the world with unique measurement methodologies. Whereas basic single- and three-phase electrical measurements, like rms voltage and current were defined long ago, many power quality parameters were not previously defined, forcing manufacturers to develop their own algorithms. With so much variation between instruments, electricians tend to waste too much time trying to under-stand an instrument’s capabilities and measurement algorithms instead of understanding the quality of the power itself!
The new IEC 61000-4-30 Class-A standard takes the guesswork out of selecting a power quality instrument. The standard IEC 61000-4-30 defines the measurement methods for each parameter to obtain reliable, repeatable, and comparable results. In addition, the accuracy, bandwidth, and minimum set of parameters are all clearly defined.
The Fluke 1760 is fully compliant with the new IEC 61000-4-30 Class-A standard, which defines the measurement methods required for each power parameter in order to obtain reliable, repeatable, and comparable results. With the GPS time synchronization accessory, data recorded with multiple instruments can be correlated with Class-A precision.
The versatile measurement algorithms and trigger settings allow the expert and general users to optimize the Fluke 1760 for each application in order to capture exactly the data required. Data can be transferred to a computer directly, or via an Ethernet network and can be retrieved during recording without interrupting the measurements.
The instrument, accessories, and power supply help you safely conduct tests with a 600 V CAT IV rating per EN 61010-1 conformity requirements. The Fluke 1760 features a double insulated enclosure, which helps protect the user, equipment, and surroundings from electrical shock. With a 2 GB compact flash memory instead of a hard disk, there are no rotating parts inside the instrument, increasing its reliability and durability for everyday use.
Developed in cooperation with power utilities, the EN50160 statistical analysis presents a summary of the quality of voltage against internationally defined limits. When a threshold is exceeded, the Fluke 1760 automatically captures voltage and current waveform data on all phases simultaneously. Nearly every power quality and power parameter is measured, including rms values, flicker, voltage dips, voltage swells, voltage unbalance, current and voltage harmonics to the 50th, interharmonics, THD, mains signaling, reactive power, transients, and power factor.
The Fluke 1760 Power Quality Recorder features easy plug and play setup for immediate use. The current and voltage probes are plugged in separately to the instrument, which automatically detects, configures, and provides power to the probes. All accessories are individually calibrated and can be shared with multiple Fluke 1760 recorders.
The Fluke 1760 includes comprehensive software for detailed power quality analysis on Windows® based PCs. In the online mode, the software enables remote instrument setup, job processing, real-time verification of actual measurement values, and data download. Data can be viewed in trend diagrams for root cause analysis or in a variety of statistical summaries. You can also generate professional reports with the Report Writer function.
