Optimized sampling technique to capture the harmonic distortion is the key for power factor measurement of nonlinear loads. Nowadays the power utilities and appliances are fully nonlinear in nature and thus the distortion of harmonics plays an important role and impacts the accuracy of many power factor measurement circuits and instruments. This study provides a cost effective design with a pro...

A measuring system evaluating a Point Spread Function generated in an ultrasonographic image by scanning a spherical target was developed. The target is moved in measuring bath filled by water over scanned volume via 3D computer controlled positioning system. A video signal obtained is converted to digital form and analyzed by original software to derive various objective parameters of the imag...
