Characterisation at Low Voltage of Two Reference Lightning Impulse Dividers
An effort is pursued by several European National Measurement Institutes to lower the uncertainties in calibration of UHV measuring systems for lighting impulse. To this end, several reference dividers are investigated as regards their accuracy both for amplitude and for time parameters. At SP RISE Research Institutes of Sweden, a 500 kV resistive reference divider has been in use since 2000. A...
متن کاملKinetics of chalcopyrite galvanic leaching using sulfate media at the low temperature in the GalvanoxTM process
In this research work, the dissolution of chalcopyrite was investigated under atmospheric pressure, with sulfate media at low temperatures, in 30°C to 50°C. In the galvanic interaction between chalcopyrite and pyrite, pyrite is used as a leaching catalyst. Effects of different parameters such as temperature, stirring speed, pyrite to chalcopyrite ratio, particle size, and solution potential wer...
متن کاملLow-temperature olivine rheology at high pressure
San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...
متن کاملGas loading of deuterium in palladium at low temperature
The experimental technique presented in this article is aimed at measuring the absorption of hydrogen or deuterium gas in a thin palladium sample while the system is at low temperature. A result for deuterium is described, consisting in the measurement of the equilibrium loading ratio X (called also D/Pd ratio, atomic), as a function of pressure, on a palladium film 3.6 μm-thick at 150 K. Value...
متن کاملElectron Mobility Maximum in Dense Argon Gas at Low Temperature
We report measurements of excess electron mobility in dense Argon gas at the two temperatures T = 152.15 and 162.30 K, fairly close to the critical one (Tc = 150.7 K), as a function of the gas density N up to 14 atoms·nm−3 (Nc = 8.08 atoms·nm−3). For the first time a maximum of the zero-field density-normalized mobility μ0N has been observed at the same density where it was detected in liquid A...
