Jurnal Nasional Teknik Elektro, 2017 Earthing systems are less well able to cause damage to electrical equipment. The risks are more current can not be optimally channeled back to earth. The smaller the resistance value, The better the earthing system. In certain soil conditions, grounding

Modeling of German Low Voltage Cables with Ground Return Path
Energies, 2021 In this contribution, measurement data of phase, neutral, and ground currents from real low voltage (LV) feeders in Germany is presented and analyzed. The data obtained is used to review and evaluate common modeling approaches for LV systems.

The Earth System: An Introduction to Earth Systems Science [PDF]
Eos, Transactions American Geophysical Union, 1999 The atmosphere, hydrosphere, biosphere, and solid Earth are the basic components of the Earth system. These different components are not separate entities; instead they interact over a broad range of spatial and temporal scales. Determining how various internal and external influences impact each component of the Earth system individually is ...

Earth system economics: a biophysical approach to the human component of the Earth system [PDF]
Earth System Dynamics, 2020 Abstract. The study of humans has largely been carried out in isolation from the study of the non-human Earth system. This isolation has encouraged the development of incompatible philosophical, aspirational, and methodological approaches that have proven very difficult to integrate with those used for the non-human remainder of the Earth system. Here,

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
