To monitor wind turbine blades

Up to 23% of wind turbine failures can be caused by blade damage, with up to 25 to 30% of wind farm operation costs spent on operation and maintenance. Current damage detection options are limited and are used on an ad hoc basis at each turbine. The new ping monitor is an innovative acoustic solution […]

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 […]
