XMR-PS

XMR-PS Shore Connection Protection Relay


XMR-PS is part of the XMORE platform, a complete range of IEDs for medium voltage applications that includes feeders, motors, generators, transformers, and capacitor banks. Thanks to its hardware and software modularity, XMR-PS is flexible and scalable in terms of applications and performance.
 

Features of the XMR-PS Protection Relay

The XMR-PS is a multifunction relay for special applications as in shore connections plants.
It can manage differents frequency and line voltages by a simple configuration switch; it is equipped with a current module to detect plugging fails between the shore main source and the ship distribution line. More over it can be used in power grids with any neutral state (isolated, earthed with high or low value resistance, earthed with Petersen coil (compensated neutral) and any
resistance, directly connected to earth) for the following typical applications:

►Protection of radial lines, transformers

With optional SW package, it is also possible to extend its
application to:

► Loop lines or long radial lines, generators or transformers
in parallel, thanks to directional phase (67) and ground (67N)
protections

► For directional monitoring of active and/or reactive power

► As multifunctional motor or generator protection
