VERY LOW FREQUENCY AC HIPOTS - ewiintl.com
The only way to field test high capacitance loads with AC voltage, like cables and motors/generators, is to use a VLF AC hipot. The lower the frequency, the less current and power needed to test high capacitance loads. Xc (capacitive reactance) = 1/2πfC. A 10,000’ 15 kV cable has approximately 1uF of capacitance. The

As the generator shaft continues to rotate, the main rotor (field) induces a voltage into the generator's main stator (armature).
