In 3Vpp+Vr,3Vpn+Vr or 2Vpp+Vr connection mode configuration, Vrchannel is filtered. In 3Vpn connection mode, Va, Vb and Vc arefiltered.VaVbVectorial SumV0VcVrVrBandpass filter[59N]Connection mode[59N] filter acivatedP3999ENaRange: Yes/NoPlease refer to “Connection diagrams” section of this Technical Guide for thecomplete description of the connection schemes.2.3.2 "VT RATIO" SubmenuThis menu is common to the MiCOM P921, P922 and P923 relays.
