Solutions for Fast, Accurate Fault Location and System Restoration
Highly accurate distance to fault results has obvious advantages and cost benefits when applied to overhead transmission lines (greater than 100KV).
Being able to dispatch repair teams to the fault site without the need for time consuming and potentially dangerous line patrols and expensive helicopter air time results in faster restoration time and improved system security.
Emergency measures invoked to guard against the possible effects of a second or third fault in the same vicinity can be expensive. There is a prime economic driver to quickly isolate the faulted section, undertake repairs and return a network to normal operational status in the shortest possible time.
