Voting
Additionally, RTD voting schemes are available and User programmable. The Voting feature must be activated and
configured within the following menu, [Protection Para\Set[x]\Temp-Prot/ RTD\Vote[x]]. Here, the setting »
Function«
has to be set to »
Active«.
Once activated, the number of channels that will be used by the voting feature is selected. This is set by way of the
parameter »
Voting[x]«. This parameter defines how many of the selected channels must be over its threshold level in
order to get a voting trip. Each individual channel must be selected or deselected by setting to either »
Yes« or »No«.
When selecting »
Yes«, the channel will be used in the voting process. Note that in order to be selected, each channel
must also be active and the RTD module itself has to be active.
If for example, Vote[x] is set to »
3«, and all channels are set to »Yes«, and if any three of the selected channels exceed
their individual threshold settings, a Vote trip will occur.
Please note that the
voting trip will be issued as a RTD trip only, if the parameter »
TripCmd Selection«
is set to »
Voting
trip«
within the Global Protection Parameters of the RTD module. The Trip has to be assigned then within the trip
manager to the Breaker.
