Figure 70: Positive-sequence undervoltage protection function
The residual overvoltage protection ROVPTOV_59G,59N provides ground-fault
protection by detecting an abnormal level of residual voltage. It can be used, for example,
as a nonselective backup protection for the selective directional ground-fault
functionality.
