Abstract
A system for monitoring electrical contacts for an overhead trolley line may include a wear sensor arranged such that an electrical contact on a vehicle or work machine for contacting the overhead trolley line is continually or periodically in its line of sight. The wear sensor may be configured to capture spatial data defining the surface profile of the electrical contact. The system may also include a data processing module configured to receive the spatial data and identify a defect in the electrical contact based on the spatial data.
