TP-MFRG
Multifunctional protection relay
The TP-MFRG is a multifunctional protection device for primary substations, with measurement and remote measurement functions, network automation, electrical service analysis and quality monitoring, recording of fault transients and remote reprogramming. It is suitable for installation in HV/MV primary substations, with isolated switch in SF6 or in air, line disconnector and ground disconnector insulated in air.
Benefits
A single configurable device to fulfil different needs
Up to two additional RIO modules management (Remote Input/Output) for the acquisition of signals coming from the field
Compliant with IEC61850 Ed.2 standard
Features
- 16 integrated protection functions, additional "built-in" control functions and graphical programming (IEC61131-3).
- Simple and intuitive interface consisting of switch control buttons, graphic color display and associated navigation keys.
- Funcionality of measurement, monitoring and advanced control.
