We optimize and extend your equipment life

HVDC Service wheel LTSA parts 2023-08-30

Modernizing an HVDC installation has been shown to extend system lifetime, improve availability and reliability, increase cost efficiency, improve performance, increase the capacity, and increase the power rating of the link.

After some years of operation, an assessment and upgrade of the equipment or systems can extend a system’s life-cycle and reduce downtime. Not only can new generation hardware and software provide new functionalities, but the upgrade can be completed within a relatively short downtime, and is a proven, efficient way to prolong high performance. Hitachi Energy is a world-leader in upgrading HVDC links, and upgrades older installations to modern systems.

Proactively upgrading a system before a severe outage occurs can save time and money. The need for upgrading depends mainly on age, the general condition of the equipment, and the potential unavailability of spare parts.
