P92x/EN FT/H42Page 22/70[59N] filterNoTechnical GuideUser GuideMiCOM P921/P922/P923P922 an P923 onlyDescription: Activates a software Band-pass filter (60 dB /decade attenuation) centered on the fundamental value (50 or60 Hz), in order to insure that residual over voltage function(59N) is immune to 10Hz & 200Hz frequency. 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.
