Abstract :
THE FOLLOWING investigation was made to study the effects of corona in producing voltage and current harmonics in transmission systems. In the early work on corona in 1910 a very complete oscillographic study was made of voltage and current. It was found that the current wave of corona loss very much resembled the excitation current wave of a transformer or iron-core reactor. A typical corona wave is shown in Fig. 1.1 This wave has a very prominent third harmonic.
