Electroluminescence in polyethylene terephthalate (PET) (impulse voltage)

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1981, 1981
Electroluminescence 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

The measurement of short-duration impulse voltages

IEEE Transactions on Communication and Electronics, 1963
A description is given of a very-small-impulse voltage divider which is insulated by compressed gas. The divider was designed for the measurement of steep-front impulse waves, and its errors have been evaluated by the step-response method, using a pressurized sphere gap.

Measurement of High-Voltage Impulses

2013
For conventional measurement of lightning, switching, chopped and oscillating impulse voltages, measuring systems with high-voltage dividers up to several megavolts have been employed for decades. They are classified as resistive, capacitive and resistive-capacitive voltage dividers.

Low Voltage Impulse Circuits

Physics, 1933
Three different types of low voltage circuits suitable for supplying impulse voltages in oscillographic work are discussed. These circuits use Thyratrons as the connecting and timing switches in place of the spark gaps ordinarily employed in transient investigations. Charged condensers are used as the source of voltage.

Peak-voltage measurements of standard impulse voltage waves

Proceedings of the IEE Part C: Monographs, 1956
The frequency spectrum of a 1/50 microsec impulse wave is obtained by the use of the Fourier transform. The corresponding frequency spectrum of the output from a simple capacitance potential divider, suitable for use up to 300 kV, is calculated from the input frequency spectrum for a 1/50 microsec wave and the frequency response of the divider ...

The measurement of the magnitude of impulse voltages using voltage comparators

Journal of Physics E: Scientific Instruments, 1971
A digital peak voltmeter is described which determines the unknown voltage by comparing it with each of 100 known constant voltages in turn. Each constant voltage exceeds its predecessor by a fixed amount. Despite the large number of reference voltages employed, only ten comparators are used.

Measurements on impulse voltages with a ballistic galvanometer

Journal of the Institution of Electrical Engineers - Part II: Power Engineering, 1942
Simple Circuits are described whereby measurements of the crest value and time of duration of the transient voltages used in impulse testing may be made with a ballistic galvanometer. Both methods of measurement have been compared with the results obtained simultaneously by a high-speed cathode-ray oscillograph.
