Phase mode The relay is connected tophase voltages U > L1 , U > L2 and U > L3 . The line voltages are calculatedusing the measured phase voltages. The residual voltage is calculatedusing the measured phase voltages. No open-delta transformer isneeded. Line mode The relay is connected to linevoltages U > 12 , U > 23 and U > 31 . The residual overvoltage stagesU > > and U > >> are not available. Line mode + U > The relay is connected to linevoltages U > 12 , U > 23 and to aresidual voltage U > . The non-measured line voltageU > 31 is calculated using the twomeasured line voltages. >
