Figure 17: Residual overvoltage protection
The residual overvoltage protection ROVPTOV provides earth-fault protection by
detecting abnormal level of residual voltage. It can be used, for example, as a
nonselective backup protection for the selective directional earth-fault functionality.
All operate signals of these residual overvoltage protections are connected to the
master trip and to alarm LED 3.
