Electricity parameters meter FESCOM

Provides observability of the operating modes of the power supply system, both the object as a whole and its individual components. It is an essential component for monitoring and managing your energy resources.

Will provide solutions to your problems

developed as a structural, hardware component of the FESCOM Digital Platform;
modular design;
designed for operation in single- or three-phase AC networks;
measures instantaneous parameters: voltage, current, power, individual values for all 3 phases and in total for a three-phase load.

Quick and easy installation

The compact dimensions of the device provide installation flexibility;
detachable measuring transformers of meters are connected to existing wires without dismantling existing electrical equipment and electrical connections;
The use of external detachable current transformers allows installation without disconnecting the load.
