This study compared the methods of determining the footwear insulation on human participants and the thermal foot model. Another purpose was to find the minimal number of measurement points on the human foot that is needed for insulation calculation. Bare foot was tested at 3 ambient temperatures on 6 participants. Three types of footwear were tested on 2 participants. The mean insulation for a...

Approximately 40% of the overall energy consumption society is consumed by buildings. Most building usage due to poor envelope performance. In regions with cold winters, corners structures typically have lowest interior surface temperature. corners, condensation, frost, and mold are common. This has a substantial effect on residents’ comfort. this study, heat loss corner envelopes evaluated, su...

Abstract This work expounds a case of insulation abnormality 220kV wall bushing end shield caused by the failure rubber seal gasket. The mechanism and causes were put forward combined with method on-site inspection, XRF analysis, infrared spectroscopy (IR) analysis thermogravimetric analysis. And suggestions for improvement sealing performance to prevent this kind defect management operation ma...
