Hello, I design below circuit (first figure) for measuring unbalance in three phase system! but there is a problem that I can't understand! when input to bridge (V(N0-V(N)) is like second figure I have a waveform like third figure in the output of bridge (V(1)-V(2))! It is half wave rather than full wave and also the amplitude is about 10 times to that of input (the probe in figure 3 is 10x) I think the waveform that I see in oscope is wrong. Do anyone know what is wrong!!?!
