Logic diagram of the overvoltage protection for phase voltage
Phase-to-phase overvoltage
The phase-to-phase overvoltage protection operates just like the phase-to-earth protection except that it
detects phase-to-phase voltages. Accordingly, phase-to-phase voltages which have exceeded one of the stage
thresholds Uph-ph> (address 3712) or Uph-ph>> (address3714 are also indicated. Beyond this, applies in
principle. Figure 2-25.
The phase-to-phase overvoltage protection can also be blocked via a binary input
>Uph-ph>(>) BLK
