TP-PMRG
Protection and measurement relay
The TP-PMRG is a directional fault detector with advanced measuring functionalities, network automation, analysis and monitoring of the electrical service quality, recording of fault transients and remote control. TP-PMRG complies with the latest E-distribuzione global standards and it is intended to be installed in secondary MV substations in order to protect and manage all the assets in a more efficient way.
Benefits
Thanks to its features TP-PMRG contributes to drastically reduce the outage time of the MV distribution network.
Compliant with IEC61850 Ed.2 standard.
Features
- 12 integrated protection functions, additional “built-in control” functions and graphical programming (IEC61131-3)
- Detection of phase-phase and phase-ground phase failures and no voltage on the line
- Advanced measurement, monitoring and control capabilities
