International Journal of Electrical Power & Energy Systems, 2020 A partial discharge (PD) measuring system has been deployed in order to identify and measure PD in a high voltage (HV) cable joint under impulse and superimposed voltages under laboratory conditions. The challenge is to enable the detection of PD during the impulse conditions. The method of measurement has been investigated by introducing an artificial

Thin Solid Films, 2019 Ion bombardment during film growth usually induces high compressive stress in compound thin film materials, resulting in rupture and failure of coated tools used in tribological applications. Hence‚ intrinsic stress generated during film growth can drastically limit the industrial appeal of deposition technologies such as high power impulse magnetron ...

Effect of Impulse Polarity on a New Grounding Device with Spike Rods (GDSR)
Energies, 2020 The characterizations of grounding systems subjected to high impulse conditions are known to be dependent on the polarity, current to peak time and discharge time, as well as the electrical properties of the soil, and the grounding electrodes themselves.

High‐latitude ionospheric response to a sudden impulse event during northward IMF conditions [PDF]
Journal of Geophysical Research: Space Physics, 2000 A high‐density structure under northward interplanetary magnetic field BZ conditions is identified at the Wind and IMP 8 satellites, both in the solar wind on August 22, 1995. A compression of the magnetosphere is observed by the GOES 7 magnetometer within a few minutes of the pressure increase encountering the magnetopause.

Seasonal Influences on the Impulse Characteristics of Grounding Systems for Tropical Countries
Energies, 2019 One of the most important parameters of the performance of grounding systems is the soil resistivity. As generally known, the soil resistivity changes seasonally, hence the performance of grounding systems, at DC and under high impulse conditions.

Stability of highly cooled hypervelocity boundary layers [PDF]
, 2015 The influence of high levels of wall cooling on the stability of hypervelocity boundary layers is investigated. Such conditions are relevant to experiments in high-enthalpy impulse facilities, where the wall temperature is much smaller than the free ...
