NPG800R

Generator protection

They provide protection for synchronors generators connected to three-phase networks.

They protect machine-generator sets ranging from a few hundred kVA to several tens of MVA.

Our NPG800R allows the modernisation of your installation of CEE 7000 relays for a very affordable cost.

CEE 7000 R case compatible

Minimises retrofitting costs

Reduces re-commissioning time

Easy to install and easy to use
