Impulse voltages chopped on front
Electrical Engineering, 1936Problems arising from testing with impulse voltages chopped on the rising fronts of the waves are discussed in this paper. A consideration of the generation and measurement of impulse voltages is presented briefly, and the problems are studied sented briefly, and the problems are studied in a discussion of the test results.

The Production of Impulse Test Voltages
Transactions of the American Institute of Electrical Engineers, 1935In performing surge tests on electrical power apparatus to determine ability to withstanding lightning or switching surges, the shape of the impulse voltage wave should be approximately the same as 1 of the 3 test wave shapes commonly in use. Methods of producing a wave shape having the prescribed time constants are described in this paper, and ...

Review of Scientific Instruments, 1966
An alternative to the Marx circuit for the production of high voltage, high current pulses is developed. It employs a water-immersed spiral-wound stepup transformer to go from a capacitor bank charged to 100 kV to an output of 1 MV. A method for using such a transformer to pulse charge a second capacitor bank efficiently without very tight coupling is ...

Standardization of impulse-voltage testing
Journal of the Institution of Electrical Engineers, 1936Following a brief resume of available information on the wave-shapes of surges on transmission lines, the wave-shapes of impulse voltages generated in the laboratory are denned and recommendations are made for the standardization of wave-shapes in order to facilitate the comparison of results obtained in different laboratories.

In power supply networks for the transmission and distribution of electrical energy at high voltage, transient voltages of more than 1 MV can occur due to lightning or switching operations. Because of their high magnitudes and short rise times, ranging from a fraction of a microsecond to milliseconds, the overvoltages cause enhanced stress on the ...

Electroluminescence in polyethylene terephthalate (PET) (impulse voltage)
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1981, 1981Electroluminescence was observed in PET when an impulse voltage was applied. The electroluminescence depended on the electrode material of the cathode and showed only a weak temperature dependence and a superlinear dependence on the electric field. The spectrum of the electroluminescence was identical with that of the photoluminescence originating from

A Study on Generation of Impulse High Voltage
SSRN Electronic Journal, 2020Impulse voltages have high voltage and high frequency of short duration. Marx generator is used for the generation of the impulse high voltages. Over these years there have been various modifications in the Marx generator with the aim to make it more compact and efficient.

Some recent developments in impulse-voltage testing
Electrical Engineering, 1940Impulse-voltage testing of electrical apparatus and circuits is a steadily growing practice and constant attention is therefore being given to improvements in testing methods. Accordingly, as progress is made it is necessary to describe recent changes.
