protective relays
THYTRONIC protective relays solution provides complete power system protection from any type of faults and system distress condition, making secure, reliable and efficient the power grid operation.
Generator Protection
XMR-D is a part of XMORE platform, the complete range of IEDs for Medium Voltage application including feeder, motor, generator, transformer and capacitor bank; it is the multifunction and comprehensive Motor and Generator protection relay, including Differential element. Thanks to Hardware and Software modularity XMR-D is flexible and scalable in term of application and performance.
Enhancements to protect and analyze power system operation in disturbance conditions:
- Up to 12 analogue inputs
- 32 sample for cycle Oscillography fault recording
- 64 sample for cycle measurement for accuracy of protection element
- Up to 0,5 class Power and Energy measurement
Enhanced Time synchronization solution for SOE recording:
- Precision Time Protocol PTP according to IEC1588
- SNTP
