1. a condenser type electric power equipment dielectric loss online test method, it is characterised in that comprise the following steps:

  • Electric current on the earth lead of on-line measurement condenser type power equipment, and described condenser type power equipment busbar voltage mutual inductanceVoltage on device;

    The coefficient of each harmonic component of described voltage and described electric current is obtained by Fourier analysis;

    The coefficient calculations of each harmonic component according to described voltage and described electric current goes out each time of described voltage and described electric currentThe amplitude of harmonic component;

    The amplitude of each harmonic component according to described voltage and described electric current, calculate condenser type power equipment equivalent capacity andEquivalent resistance;

    Equivalent capacity and equivalent resistance according to described condenser type power equipment are calculated dielectric loss angle tangent and export.
