XMR-P 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-P is flexible and scalable in terms of applications and performance.
Features of the XMR-P Protection Relay
The XMR-P multifunction relay is 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
- As a CEI 0-16 certified General Protection System ( SPG), with measurement inputs from inductive CT-VT or from ThySensor
- Disconnection of self-producers from the electrical distribution network (LoM - Loss of Main); in particular, the version with inputs from ThySensor, is CEI 0-16 certified as SPG (general protection system) and integrated SPI (interface protection system).
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.
