Feasibility analysis of neutral grounding by small reactor of HVDC converter transformer
Energy Reports, 2022 Nowadays, the scale of power grid is remarkably increasing and there is a continuous reinforcement of AC–DC hybrid systems. Thus, the single-phase grounding fault currents on the AC grid-side of rectifier and inverter stations increase significantly ...

The Earth systems and Earth science informatics [PDF]
Earth Science Informatics, 2008 Earth scientists collect, store, manage, process, and organize data about the different components of the Earth system, and about natural and simulated processes. The transition from data to information is achieved through computation, visualization, and other processes that make the data more meaningful to the scientists.

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.

Earth Observing System AM1 mission to Earth [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 1998 In 1998, NASA launches EOS-AMI, the first of a series of the Earth Observing System (EOS) satellites. EOS will monitor the evolution of the state of the earth for 18 years, starting with the morning observations of EOS-AM1 (10:30 a.m. equatorial crossing time).
