Abnormal Operation Due to High-Temperature Degradation of Coke

degradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...

RPC operation at high temperature

The resistive electrodes of RPCs utilised in several current experiments (ATLAS, CMS, ALICE, BABAR and ARGO) are made of phenolic/melaminic polymers, with room temperature resistivities ranging from 10 O cm; for high rate operation in avalanche mode, to 5 10 O cm; for streamer mode operation at low rate. The resistivity has however a strong temperature dependence, decreasing exponentially with ...

Performance loss among workers due to heat stress in high-temperature workplaces

Background: Heat stress is one of the harmful factors present in many workplaces. It can lead to performance loss and low functionality of the labor force. Therefore, the aim of this study was to evaluate exposure to heat stress and its consequent performance loss among workers functioning in indoor high-temperature workplaces. Materials and Methods: This descriptive, analytical study was co...
