  • Apparatus and method for testing stator core of generator
    Patent number: 10502787
    Abstract: An apparatus and a method for testing a stator core of a generator are presented. The apparatus includes a power supply. The power supply provides an excitation current having a base frequency. A frequency convertor is connected to the power supply. The frequency convertor converts the base frequency of the excitation current to an excitation frequency that is greater than the base frequency. An excitation cable connects the frequency convertor to a rotor at two axial ends. The rotor is excited by the excitation current with the excitation frequency as a single excitation winding for simulating an operation state of the generator causing hot spots on the stator core without overheating the rotor.
    Type: Grant
