3.14 Zero Sequence Overvoltage Protection

3.14.1 Zero Sequence Overvoltage Protection Theory

On a healthy three-phase power system, the addition of each of the three-phase to earth voltages

is nominally zero. However, when an earth fault occurs on the primary system, the balance is

upset and a residual voltage is produced. Hence, a zero sequence overvoltage protection can be

used to offer earth fault protection on such a system.

The residual voltage could be measured at the secondary terminals of a voltage transformer
having a “broken delta” secondary connection, or it can be calculated from the three phase

voltages; which is decided by the setting [Opt_3U0].

This relay provides a two-stage zero sequence overvoltage protection with definite time delay

characteristics. The two stages have same protection logics.

The following figure shows the logic diagram of the stage 1 zero sequence overvoltage protection.

” is the setting [59G1.t_Op], the time setting of the stage 1 zero sequence overvoltage

protection;

[59G1.En] is logic setting of the stage 1 zero sequence overvoltage protectio n.

[59G1.En1] is the binary signal for enabling the stage 1 zero sequence overvoltage

protection;

[59G1.Blk] is the binary signal for blocking the stage 1 zero sequence overvoltage protection.
