The Zeta transformer and auxiliary circuit equipment

The paper outlines the design and construction of the Zeta high-power pulse transformer and its associated core-biasing circuit. Details are given of the pulse-shaping reactor and non-linear resistance unit with reference to the circuit calculations made on a high-speed digital computer, and also of the saturable reactor which assists in the switching operation and the current transformers and voltage dividers which were supplied. The design of the stabilizing axial-field winding is also discussed.
