Voltage release via remote control connection from the PCC
This method has to be used, if the PCC is on the HV side.
This method can be used, if the PCC is on the MV side.
If
reconnection
should be done via remote control signal from the PCC:
In the menu [Protection Para\Set[x]\Q->&U<\General settings] the parameter
»PCC-Release Fc« has to be set to
»active«. With this setting the voltage release signal from the PCC is used (e. g. signal via digital input)
Additionally the parameter
»Reclosure Release Cond« in the menu [Protection Para\Set[x]\Q-
>&U<\Reclosure\Reclosure Trigger] has to be set to
»PCC (Extrernal Release)«
Also the remote control release signal has to be assigned to the parameter
»PCC-Release« in the menu
[Protection Para\Global Prot Para\Q->&V<]
Voltage release by measured voltage values
This method can be used, if the PCC is on the MV side.
If the PCC is on the MV side, the device can measure the phase to phase voltages on the mains side and decide if the
mains voltage has stabilized sufficiently for reconnection.
For this method the parameter »
V Ext Release PCC Fc« in the menu
[Protection Para\Set[x]\Q->&V<\General settings] has to be set to »
inactive«
.
Additionally the parameter »
»Reclosure Release Cond«« in the menu
[Protection Para\Set[x]\Q->&V<\Reclosure\Reclosure Release] has to be set to
»
Internal Release«
