Directional phase overcurrent protection, four steps OC4PTOC
(51_67)
Prepare the IED for verification of settings outlined in Section
Values of the logical signals for OC4PTOC are available on the local HMI under Main menu/Tests/
Function status/Current protection/PhaseOverCurrent4Step(51_67,4(3I>)) /
OC4PTOC(51_67;4(3I>)):x, where x = instance number.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
