Abstract :
The paper presents the monitoring of the power quality of an underground electric line fed by a high voltage transformer station 110/10 kV and a subsequent earthing fault situation followed by a short circuit. The monitoring process was performed using a power quality analyzer. The analysis of the evolution in time of the phenomena highlights the variations of the voltage in the medium voltage bus of the transformer station during the failure situation.
