Research on voltage SAG behaviour and its effect on load / Azriyani Md Yusoff

This paper presents about voltage sag characteristic and behaviors through different types of experiment and data collection. Voltage sags is one of the interruption that reduce power quality performance. According to International Electrotechnical Commission (EEC) , voltage dip is sudden reduction in the supply voltage to a value from 90% and 1% of the declared voltage and it will be followed by a recovery between 10ms and 1 minute later. While for Institute of Electrical and Electronics Engineers (IEEE) Standard 1366, a voltage drop will be called sag only if sag voltage is between 10% to 90% of the nominal voltage. This research is useful to planners or design engineer towards planning and development to consider the most efficient way to reduce voltage sags.
