Grounding Resistance and Grounding Impedance of Horizontal Bundled Conductor Grounding Electrodes.

IEEJ Transactions on Power and Energy, 2003
It is well known that increasing conductor radius of grounding electrode results in decreasing grounding resistance, but the decrease extent is very little compared with the increase extent. However, when bundled conductors are used for grounding electrode, lower grounding resistance is expected to be obtained. Thus the bundled conductors of horizontal

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

Advanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

Thermoelectric Modules Incorporating MgAgSb and Mg3(Sb,Bi)2 Synthesized Using a Melting Method

Advanced Engineering Materials, EarlyView.
A scalable synthesis method for a thermoelectric material of MgAgSb is established. A thermoelectric power module of MgAgSb/Mg3(Sb,Bi)2 is fabricated, showing the conversion efficiency of 7.4% at ΔT = 315 K. The performance is comparable to conventional Bi2Te3 modules when they are operated with an air‐cooled heat exchanger.
