I think the requirement is to produce Op and Tr signals when there is an overvoltage on all 3 phases = an AND function.
As standard, the PTUV.Op is an OR function - at least one phase is overer-voltage

Proposal : add a setting
NumPhsStr ENG Number of phases to start detection: values 1,2,3. If the DO is not present detection starts when one phase is over the threshold voltage
See issue #580

Opinion of the TFUF group is that this is not correct statement. Because this implies that there will be no Operation/Trip in case that there is single or two phase pickup/start.
Semantic of Op.general or Tr.general will be dealt in TF 7-500.
User is requiring that there is single attribute 3ph op/tr.
