Modifying and modernizing protection devices

NSE AG's core competency is replacing medium and high-voltage protection technology. We are currently modernizing primary and secondary protection devices in existing substations. At the same time, we are carrying out mechanical adjustments to control cabinets and on-site wiring of secondary technology. Once conversion has been completed, you will of course receive updated schematic drawings and complete test documentation on the protection systems.
We will gladly take on the roles of on-site project management and implementation when you decide to convert and modernize your systems. You can also count on us as a partner when regenerating your systems.
Our in-house protection relays from the SAVE family were made especially as an alternative to Sprecher&Schuh RN1 and RN1.2 protection relays. Our RN1 and RN1 plug connector has a constructive design.Maintaining 2 protection relays and improving the components' functionality. In this way, it is possible to modernize these devices using modern SAVE protection relays with a minimal amount of time.  It only takes a couple of adjustments before our SAVE systems can be used in every existing system in your extremely compact construction.
