Implementation of a non-conventional method to characterize voltage sags and swells

open access: yesDyna, 2016
Voltage sags and swells are among the power quality disturbances that represent the biggest economic losses for affected users. It is therefore necessary to undertake a suitable characterization of those events to conduct studies that permit the causes ...
