Abstract Asset management of instrument transformers (ITs) has gained momentum in recent years due to their large population in the network and the potential adverse impacts of their increasing number of failures. This study investigates the failure

In this paper, we present a new approach to use machine learning (ML) for the calibration of a physical model allowing the reproduction of the vibratory behavior of an overhead line conductor. This physical model known as Strip Theory (ST) has the ad

The mechanical behavior at contact points in high-voltage electrical cable conductors is simulated to find where damage may occur. The presented approach is based on a numerical model that is referred to as the wire model. The critical zones are dete

This work focuses on the study of the phenomenon of vortex-induced vibrations in overhead lines under the effect of weak winds. Full three-dimensional simulation is not feasible because of the high length to width aspect ratios of the overhead lines.

Fretting fatigue crack propagation in aluminium strands was investigated through experimental tests and FEM simulations. Fretting fatigue tests revealed that crack nucleation predictions are not sufficient to fully predict the total strand failure, a

Asset management is a major challenge for RTE (Reseau de Transport d’Electricite), the French TSO (Transmission System Operator) since electrical grid component maintenance and renewal represent important economic issues. Thus, improved assessment
