Measuring the operate value for the zero-sequence function

M1405-72 v7

Simulate normal operating conditions with the three-phase currents in phase with their

corresponding phase voltages and with all of them equal to their rated values.

Slowly decrease the measured voltage in one phase until the BLKU signal appears.

Record the measured voltage and calculate the corresponding zero-sequence voltage

according to the equation.

Observe that the voltages in the equation are phasors.
