ABB G1LA NSD570 1KHW000592R000 Teleprotection Equipment
Description:
NSD570 is designed for the transmission of protection commands over all kinds of communication media, like copper wires, optical fibers, analog and digital channels of optical networks and microwave radio links, as well as Ethernet/IP based telecommunication networks.
Depending on the protection scheme in use, the command signals trip the remote circuit-breaker either directly (direct tripping) or are first enabled by the local protection device (permissive tripping). Other protection schemes involve tripping prevention by the local protection device (blocking).

A fundamental requirement in all these applications is that command signals are communicated reliably at the highest possible speed. In the event of a fault on the protected unit, the command signals must be received at the remote end in the shortest possible time even if the channel is disturbed by the fault (dependability). 

On the other hand, interference on the communications channel must never cause unwanted operation of the protection by simulating a tripping signal when there is no fault on the power system (security). 

The most important performance features of a teleprotection equipment are therefore transmission time, dependability and security. From the communications engineering point of view, the bandwidth or data rate a teleprotection equipment occupies must also be taken into account.
