TP-PMRG

Protection and measurement relay
ASK A QUOTE

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.
