| Abstract: | The pithy fomula, which applied to estimate the electrical parameter of three-phase asynchronous motor during star-triangle starting, was introduced. It included the judgment of starting condition, starting current, starting torque, starting time and estimated setting current of the thermal protector. Physical meaning of the pithy fomula was analyzed, being very helpful to increase the efficiency of field installation, operation and maintenance. |
