GE Multilin L30 Line Current Differential System 5-2015 SETTINGS 5.6 GROUPED ELEMENTS5c) PHASE OVERVOLTAGE (ANSI 59P, IEC PTOV)PATH: SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) VOLTAGE ELEMENTS PHASE OVERVOLTAGE1(3)There are three phase overvoltage elements available. A phase overvoltage element is used as an instantaneous elementwith no intentional time delay or as a definite time element. The input voltage is the phase-to-phase voltage, either mea-sured directly from delta-connected VTs or as calculated from phase-to-ground (wye) connected VTs. The specific voltagesto be used for each phase are shown below.Figure 5–84: PHASE OVERVOLTAGE SCHEME LOGICIf the source VT is wye-connected, then the phase overvoltage pickup condition is for VAB, VBC,and VCA.
