Abstract A new detection method for three-phase voltage based on 3D-space normal vector is presented in this paper. This new method has some advantages such as quick detection, simple calculation and adaptability for unbalanced voltage. Simulation and experiment is given and the results show that the method has very good speed and accuracy for detection of unbalanced three-phase voltage.

Key words： 3D space normal vector unbalance voltage sag detect LVRT
