Assessing Risk Factors for PD-Activity in 24 kV Secondary Substations Using Machine Learning
In Sweden, surface partial discharges (PD) in 24/0.4 kV secondary substations have been identified as a reliability concern, with the potential to cause equipment failures. This study used inspection data from over 500 substations, combined with asset and environmental information, to develop features for predicting PD-related faults in cable terminations.
