Abstract :
This article presents an online monitoring system for power transformers developed and evaluated on several transformers at EDF. It combines acoustic, electrical and chemical measurements of partial discharges to establish a diagnostic of the transformers and generate an alarm if admitted thresholds are exceeded. This system is modular and can be used for monitoring for several months or to make a diagnosis in a few days
