Analysis of PQ waveform for optimum data transmission over IEC 61850 communication standards

Power-quality phenomena such as voltage sag are observed at several substations to obtain an overview of the general network state and quality of power supply. Presently, collections of data from disturbance recorders involved long and tedious downloading process through telephone line. Usage of int...
