Self-neutralization of inductive symmetrical load in a three-phase network
The article is concerned with the mechanism of exchanging reactive power in a system formed by a synchronous electrical machine and a part of a three-phase network. It is shown that the symmetrical inductive load in the system causes free harmonic oscillations of electric current, and any two phases together become a condenser for the third one. Thus, there is no need in generating reactive power because the source of any phase is a set of inductive elements included in the circuit of the other two phases
