Unipower – About Power Quality
Published by Unipower AB, Metallgatan 4C, 44132 Alingsås, Sweden. Email: info@unipower.se Power quality is a generic term for disturbance-free electricity supply. Deviation from voltage sinusoidal waveform (50 Hz), which may result in equipment being disturbed or damaged, is to be regarded as a power quality disturbance. This means that the more sensitive equipment you connect toContinue reading “Unipower – About Power Quality”
