This circuit can determine the phase relationship of the AC power. FF1 is a D flip-flop in the dual D flip - flop 4013. The three ends (U, V, W) in the circuit is directly connected to the three - phase power supply. If the phase relationship of the AC power supply is arranged clockwise like U, V, W sequentially arrangement, the green LED D4 is lit; if the phase is counterclockwise arrangement, the red light emitting tube D3 is lit.
