Condition-based assessment of on-load tap changers

On-load tap changers (OLTCs) are a crucial element of utility networks, as they must operate in a precise fashion in order to maintain a constant voltage output. This must be achieved regardless of variation on input or load. OLTCs have been a weak link in many networks, as they deteriorate over time due to mechanical […]

The use of robots in the maintenance of overhead lines

Strategic assets, such as electricity transmission grids, must be operated in a safe, predictable and reliable way. To do so, best practices in the operation and maintenance of transmission networks must evolve to respond to the changing context of pressured grid operators: operation and maintenance standards, laws and regulations, increasing loads, commercial exchanges, etc. This […]
