Abnormal Voltages within Transformers

Transactions of the American Institute of Electrical Engineers, 1919
Mathematical analysis is made of a rectangular wave impinging upon a transformer winding and quantitative values deduced of the resulting internal voltage stresses in terms of transformer constants. It is shown that the conclusions also apply in part to abrupt impulses and approximate idea is given of the reaction of a transformer to high frequencies ...

Capacitor voltage transformers

Journal of the Institution of Electrical Engineers, 1936
The paper describes in a general way that class of voltage transformer which the authors propose should be termed the "capacitor voltage transformer" as distinct from the conventional electromagnetic voltage transformer. No claim is made for presenting any new principles of design, the main purpose of the paper being to establish a wider understanding ...
