Lightning, Surge Protection and Earthing of Electrical

Lightning arrestors belong to the general equipment egory of surge protection devices (SPD). The arrestors used in HV circuits are essentially nonlinear resistors placed within porcelain housing and present a very high resistance at normal voltages. They are designed to break down at voltages above the highest system operating voltage (but

Zeolites – Wissensplattform nanopartikelfo

Zeolites were discovered in 1756 by Axel Frederick Cronstedt. They consist of the basic building blocks silie, aluminate and phosphate. They belong to the group of aluminosilies. The aluminium, silicon and phosphorus atoms are connected via oxygen atoms in all three spatial directions.

Silicon Carbide SiC - STMicroelectronics

Silicon Carbide (SiC) is a wide bandgap material. Wide bandgap technologies have many advantages compared to Silicon. Operating temperatures are higher, heat dissipation is improved and switching and conduction losses are lower. However, wide bandgap materials are more difficult to mass produce compared to silicon based ones.
