Used to monitor the entire metering chain:

• CT and VT sensors
• connection
• Sepam analog inputs.

Monitoring includes:

• consistency checking of currents and voltages measured
• acquisition of phase or residual voltage transformer protection fuse blown contacts.

In the event of a loss of current or voltage measurement data, the assigned protection
functions may be inhibited to avoid nuisance tripping
