Control and monitor grid load and provide effective damage prevention

Could the Valcap® power cable monitoring software system cut your business costs and improve electrical grid safety for you? This innovative solution offered by NKT works in partnership with your existing cable software to give you better control over efficiency, performance, safety and management of power networks.

Load restrictions of submarine cables due to thermal limits are a significant problem if the required energy cannot be transported. Especially wind farms with high load variation due to varying wind situations require the flexible usage of the available cable capacity. If windmills have to be shut down, significant cost is involved due to lost revenues. On the other hand the damage of submarine cable due to overheating also leads to huge cost for cable replacement. The VALCAP® Load Management System is a combination of hardware and software that uses temperature information of power cables acquired by fiber optic temperature measurement together with current load information to utilize the full capacity of submarine cables. Automatic warnings are created if a cable could be at risk of being damaged due to high load situations.

Damage to underwater cables due to shipping activity is a significant global problem. Repairs to damagedcables are very expensive and availability of suitable repair vessels is difficult to guarantee. The problem is likely to get worse as more cables are installed for offshore wind farms and marine turbines. The VALCAP® Security Monitoring System is a software application that is using multiple functions such as acoustic monitoring, to safeguard against and warn as well as detect possible damages. In case a cable may be at risk, the system automatically provides a warning to prevent possible damages.

With our vast experience in power cable monitoring, we also provide specific monitoring services in case of special requirements. Our experts will evaluate your needs together with you in order to find the best solution to your individual challenge. In doing so, we always focus on quick and efficient solutions while always keeping long term customer value in mind.
