The systems are on the crossings over Fyksesundet, Granvinsfjorden and Osafjorden.

Repeated wind-driven vibration may gradually wear conductors, dampers, insulators and other components.

Continuous monitoring supplements calculations, visual inspections and shorter measurement periods used previously.","The monitoring equipment was developed through the D-fjord research and development project. Statnett says conditions can vary between fjords even when lines and dampers are similar. At one Hjørundfjorden crossing, the company found that phases of the same line type moved differently.
