The Dewesoft Power Quality Analyzer and Meter is a flexible DAQ solution. Firstly, it combines power and energy loggers as well as several measurement instruments into a single device. This has several advantages for the measurement process. Including Data synchronisation, raw data logging, easy to use intuitive software for all measurement and analysis tasks at a low cost and to IEC 61000-4-30 Class A Standard.
Secondly, different power quality parameters describe a deviation of voltage from its ideal sinusoidal waveform at certain frequencies. Deviations can lead to disturbances, outages or damages of electrical equipment connected to the grid. Therefore, the main parameters that power quality focuses on are harmonics, unbalance in electrical systems, flicker, voltage changes and peaks, transient recording and frequency behaviour.
So, it is important to permanently track these parameters. Ideally, starting from the development phase of the electrical equipment and up until live operation and beyond. Continuous monitoring of several areas of the electrical grid will assist with prevention of major faults and correct quality disturbances.
These systems can assist the analysis of a range of energy sources: Wind Power, Solar (Photovoltaic), Fuel Cells, Biomass, Geothermal power, Hydro Power and Conventional Power Plants.
The Dewesoft power quality analyser is a vital piece of equipment. In this single device it measures:
- Harmonics and THD up to 150 kHz
- Interharmonics & higher frequencies
- Flicker, Flicker Emissions, RVCs
- FFT, Harmonic FFT, Water FFT
- Symmetrical Components
