To widen its portfolio, Prysmian Electronics is now focusing on a set of new applications of its technologies. “As far as the products under development are concerned – Candela says – we will focus mainly on Partial Discharge measurements applied to Direct Current (DC), because, market-wise, this is the segment in which Prysmian Group is more active and the undisputed leader. As a matter of fact, in terms of diagnostics capabilities, we are the only ones who can offer this type of service. Furthermore, we will focus also on taking another step to integrate our monitoring systems with cable systems, like, for instance, the new Smart Link-box. It consists in the integration – within the link-boxes installed in power transmission and distribution cable systems – of a monitoring systems capable of providing all functioning parameters without any invasive action on the link-box itself. We want to follow this route and keep on increasingly integrating electronics within the cable rather than outside, as it was, instead, in the past. We are aiming at having a growing number of accessories, components and devices integrated within the cable system”.
Link-boxes have been existing for more than half a century, but so far, they have always been passive tools. They are steel boxes placed by each joint along the cable system’s route that host cable earthing connections and surge arresters, which play a key role in the case of lightning bolts or short circuits. Until a short time ago, should a fault occur, the link-box had to be opened to make the necessary checks and then closed. This activity should be carried out every six months “but it’s a complicated operation – adds Candela – and often it does not take place unless a fault occurs. The application of electronics to these objects can generate remarkable advantages because it allows to gather information in real time, always. It also allows to carry out interventions only if a real malfunctioning is detected. This is the reason why this object is so important. In the past, the maintenance plan did not follow a systemic pattern. Today the quality approach adopted allows to improve the entire process”.
