Thermal Profiles of High-voltage Capacitor Units [PDF]

2019 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2019
High voltage capacitors are useful in power factor correction, harmonic filtering, energy storage and voltage support for modern electrical power systems. Even modest failure rates can be compounded by large numbers of assets deployed in high capacity installations, and as fuses are positioned internally or omitted in pursuit of more efficient ...

Quasilinear spin-voltage profiles in spin thermoelectrics [PDF]

Physical Review B, 2011
Recent experiments show that spin thermoelectrics is a promising approach to generate spin voltages. While spin chemical potentials are often limited to a surface layer of the order of the spin diffusion length, we show that thermoelectrically induced spin chemical potentials can extend much further in itinerant ferromagnets with paramagnetic ...
