A study on voltage sag in industry system with adjustable speed drive
(Universiti Malaysia Perlis (UniMAP), 2008-03-15)
The awareness of electric power quality has increased over the past decade as electronic equipment has become more susceptible to power disturbances. The most distruptive power disturbances is voltage sags. Voltage sags ...
Testing of contactors under voltage sag and non-sinusoidal voltage conditions
(Institute of Electrical and Electronics Engineers (IEEE), 2010-11-29)
Sensitivity of electromagnetic contactors for voltage sags and non-sinusoidal voltage supply has been carried out by laboratory testing. Effects of sag characteristics such as; sag magnitude, sag duration and point on wave ...
Comparison on performance of voltage sags miligation techniques
(Universiti Teknologi MARA (UiTM), 2009-06-03)
The increasing use of sophisticated electronics, high efficiency variable speed drive, and power electronic controller, power quality has become an increasing concern to utilities and customers. Voltage sags is the most ...
An analysis on power quality measurement and monitoring techniques for nonlinear load
(Universiti Malaysia Perlis (UniMAP), 2008-03-15)
Electric power quality is an aspect of power engineering that has been with us since the inception of power systems. The measurement of the quality of the electric power in a network is therefore becoming an urging need ...
