Overcurrent, earth-fault and phase
discontinuity protection of an
overhead line feeder
Figure 3.1-1 Three-phase overcurrent protection, earth-fault protection and
phase discontinuity protection of an overhead line feeder. The earth-fault
current is measured with a residual current connection of the current
transformers. The analog mA output can be used to show the load current of
one of the phases. The signal can be wired to a local meter or to an
automation system
