Abstract :
AN ANALYSIS of the theory of the 3-wire d-c. generator using a 2-phase static balancer is presented in this paper with the particular object of explaining the very large unsymmetrical magnetizing current peaks which occur in the balancer windings. These peaks are evidence of unsymmetrical flux variation attaining high values of flux density; and as their value may be equal to, or greater than, the total unbalanced current in the neutral wire of the system, they have a pronounced effect upon the r.m.s. value of the currents, and therefore upon the heating, in the balancer phases. They also cause marked pulsations in the terminal voltages of the machine.
