Base Unit

Functions Available According to

Connected Voltage Inputs

The phase and residual voltages that Sepam™ measures determine the availability

of some protection and metering functions.

The table below gives the voltage input connection variants for each protection and

metering function that depends on measured voltages.

Example:

The directional ground fault protection is ANSI 67N/67NC. It uses residual voltage

Vr as a polarization value.

It is operational in the following cases:

b measuring the three phase-to-neutral voltages and calculating the variant,

(3 V

+ VrΣ, variant 1)

b measuring residual voltage Vr (variant 5).

Directional ground fault protection is ANSI67N/67NC.

The protection and metering functions not appearing in the table below are available

regardless of the voltages measured.
