摘要
It is the first time to use the test methods for low voltage release study, the paper used experiment method to test operation characteristics at different amplitude, phase and duration, then the paper built the model of tripping capacity.Firstly, the paper designed the experiment program, which concludes platform, parameter and procedure.Secondly, five types low voltage releases that are mainly used in market are tested, showing that amplitude, phase and duration determine the tripping capacity and forming 205920 sets of experimental data.At last,the experimental result were extremely treated and the paper used curve fitting method to obtain the function between amplitude and duration at different phase, and the function between phase and duration at different amplitude, namely constructed the tripping model of low voltage release under voltage sag from the dimension of phase and amplitude.
