VERY LOW FREQUENCY AC HIPOTS - ewiintl.com
www.ewiintl.comThe 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

GENERATOR
www.marathongenerators.com(armature) to produce AC voltage even when the exciter stator (field) is not powered.This AC voltage is rectified to DC by the rotating rectifier assembly and fed directly to the main rotor (field). As the generator shaft continues to rotate, the main rotor (field) induces a voltage into the generator's main stator (armature).
