Notes on the measurement of high voltage [PDF]

Proceedings of the American Institute of Electrical Engineers, 1916
A briet account is given of some experiments made to determine mine the relative accuracy of certain methods used in measuring high voltages. The methods comprise the use of a tertiary (or voltmeter) coil in the high-tension transformer, the direct measurement of voltage by a crest voltage meter and the derivation of the high-tension pressure from the ...
