Issue: contact wire wearing under splice
Risk: main overhead contact wire failure, dewirement, damage to rolling stock, infrastructure with health and safety of personnel at risk
Value: early intervention and prevention of dewirement from pantograph catching tension wire
Electrified overhead wiring networks are comprised of many lengths of cable that are joined or spliced together by clamps. Over time, through use and wear, clamps can work loose and cables may become kinked. This can result in abnormal wear rate of the contact wire. The network maintainer has been able to precisely identify when the contact wire has become kinked and show accelerated wear to the overhead line and rollingstock pantographs. As such, an infrastructure failure is prevented through early and precise fault detection.
