Description
motor starting using star delta device
my project is about making device that can be star 3 phase ac induction motor with high power using star delta method , the advance of my device is that can be compact ,low coast , and fast to wire it in the panel , with also thermal protection that the traditional using of contactor
Code
the code

const float ADC_REF = 5.0;
