The measurement of high voltages, with special reference to the measurement of peak voltages
Journal of the Institution of Electrical Engineers, 1930Two methods of measuring peak voltage have been invetigated. In the one method a condenser divider is used, and the voltage on the low-voltage arm of the divider is rectified. In the other the current through a condenser connected across the voltage to be measured is rectified, and the mean current so obtained is a measure of the peak voltage across ...

High Voltage Measurements at Niagara
Transactions of the American Institute of Electrical Engineers, 1908In the autumn of 1896, the writer of this paper undertook an investigation of the phenomena existing when transmission line conductors are subjected to high alternating voltages. The work was carried on near Telluride, Colorado, and extended over a period of about a year. The results of this work were embodied in a report made by the writer in 1897.

The measurement of high surge voltages
Electrical Engineering, 1933With the application of surge tests to high voltage electrical apparatus, the question of the measurement of high-surge voltages has become a subject of prime importance. It is accordingly desired in Part I to show the practical work done in the laboratory at Sharon to calibrate the measuring devices, and in Part II to study the more interesting ...

14th IEE Microwave Measurements Training Course, 2005
The majority of signal amplitude or level measurements made at RF and microwave frequencies are measurements of power rather than voltage. Voltage measuring instruments such as RF millivoltmeters are still in frequent use but are nowadays less common than in the past.

Voltage and current measurements
1990The difficulties associated with voltage and current measurements increase with frequency and most voltmeters and ammeters are restricted to the region below 1 GHz [1-4]. Above 1 GHz voltages and currents in transmission lines can be deduced from a knowledge of the power flowing in the line, the characteristic impedance, and the reflection coefficient ...
