History of A-C wave Form, Its Determination and Standardization
@article{Bedell1942HistoryOA, title={History of A-C wave Form, Its Determination and Standardization}, author={Frederick D. Bedell}, journal={Transactions of the American Institute of Electrical Engineers}, year={1942}, volume={61}, pages={864-868} }
With the birth of the transformer and the first distribution of alternating currents, wave form assumed interest, and methods were developed for its determination, chiefly the point-by-point method of instantaneous contact, mechanical oscillograph, cathode-ray oscillograph, and the oscilloscope with stabilized time axis. The point-by-point method, by which were made the first major contributions, is now practically superseded by oscillograph and oscilloscope, each finding increasing use in its…
