Measurement Characteristics of Voltage in Practice and Possibilities for Improvement of Voltage

Published by Alena OTCENASOVA, Juraj ALTUS, Petr HECKO, Marek ROCH,Slovakia, University of Zilina, Faculty of Electrical Engineering, Department of Power Electrical Systems Abstract. Worsened quality of supplied as well as demanded electricity causes in reality a large financial loss. The main quality parameters monitored today are voltage dips and interruptions. In this context there areContinue reading “Measurement Characteristics of Voltage in Practice and Possibilities for Improvement of Voltage”

PQ Analysis: Power Interruptions

Published by testguy, November 23, 2019. Website: testguy.net, Power Interruptions The most simple type of power quality problem occurs when power delivered to an electrical load goes away, this is called a “power interruption.” The different types of power interruptions are classified according to their duration. A momentary interruption is a complete loss of voltage on one or moreContinue reading “PQ Analysis: Power Interruptions”
