Characterising Power Quality Disturbances Resulting from Expulsion Fuse Operation

This paper presents easily implementable tools 

for characterization and diagnosis of electrical 

disturbances caused by fuses operation. A methodology is 

described, where the use of some descriptors allows 

identifying electrical disturbances associated with the 

expulsion fuse operation. This paper aims to provide new 

tools for assessing the power quality, characterizing and 

extracting information from the current and voltage 

records obtained by monitoring in electrical distribution 

systems. MATLAB is used for validating this methodology, 

receiving voltage and current records of simulated  events 

in ATP-EMTP and also real events as input.
