Operation principle
Zero and negative sequence detection
The zero and negative sequence function continuously measures the currents and
voltages in all three phases and calculates, see figure 130:
• the zero-sequence voltage 3V0
• the zero-sequence current 3I0
• the negative sequence current 3I2
• the negative sequence voltage 3V2
The measured signals are compared with their respective set values 3V0PU and 3I0PU,
3V2PU and 3I2PU.
The function enable the internal signal FuseFailDetZeroSeq if the measured zero-
sequence voltage is higher than the set value 3V0PU and the measured zero-sequence
current is below the set value 3I0PU.
The function enable the internal signal FuseFailDetNegSeq if the measured negative
sequence voltage is higher than the set value 3V2PU and the measured negative
sequence current is below the set value 3I2PU.
