Transmission networks
With KOMBISAVE+, NSE offers a powerful protection platform for complex transmission networks.
The devices combine distance, differential and earth fault protection functions with state-of-the-art communication technology and high operational reliability – developed for use in high and extra-high voltage systems.
The polygonal distance protection enables precise fault detection over long distances and ensures reliable network protection.
In combination with AWE (auto-reclosing) and ground fault detection, the system warrants maximum selectivity and short reconnection times – even in widely branched transmission networks.
Polygonal distance protection with under-impedance starting and load discrimination
The single-pole interaction scheme clearly shows the protection and control functions in transmission networks.
Our high-performance protection devices combine state-of-the-art protection algorithms, fast communications and intelligent bay control – for maximum availability in grid operation.
