Power quality can be defined as the interaction of electrical power with electrical equipment. If all the equipment operate correctly and reliably without being damaged or stressed, the electrical power is of good quality. The most important parameters to technically define power quality are: - Voltage magnitude - Power - Frequency - Voltage events (sags, swells, and interruptions) - Harmonics and interharmonics - Flicker Power quality measurements and analyses are important to diagnose power system problems. Without correct and adequate measurements, these problems may be overlooked or misapprehended. Therefore, using high speed and accurate power quality analysers is crucial in the measurement process. Moreover, the diagnosis stage needs experience on different types of load characteristics and problems.
Power Quality Analysis
We take measurements and analyse the results, or we examine the existing measurements and offer power quality solutions to problems of our customers. The power quality measurements are taken and analyses are made according to the following specifications:
» In compliance with IEC 61000-4-30 » IEEE Standard 519-1992 compatible » Synchronous measurements in time on separate devices » High resolution, high sample rate
