On Zone Models For Flashover [PDF]

Fire Safety Science, 1997
A zone model for the developmeii~ of a fire in a single compartment with one opening is studied to obtain explicit formulae for the critical conditions for occurrence of flashover and its temporal characteristics. In addition to previous studies, generalisation is presented for walls of arbitrary thermal inertia.

Enhancing Hydrophobic Stability of Silicone Rubber Insulators Under High‐Voltage Direct Current Stress Through Optimised Nano‐Fumed Silica Surface Area: A Dynamic Drop Test Study

High Voltage, EarlyView.
ABSTRACT The long‐term hydrophobic stability of silicone rubber (SiR) insulators is essential for their reliability in high‐voltage direct current (HVDC) applications. This study investigates the effect of nano‐silica fillers with varying specific surface areas (SSA = 120, 200 and 300 m2/g) and different concentrations of alumina trihydrate (ATH ...
