    Effect of micro-H 2 O and micro-O 2 on the decomposition ...· In recent years, heptafluoroisobutyronitrile (C 3 F 7 CN) has been proved to be a potential eco-friendly insulating medium to replace sulfur hexafluoride (SF 6, the strong greenhouse gas).In this paper, the effect of micro-H 2 O and micro-O 2 on the decomposition of C 3 F 7 CN was investigated based on the reactive force field molecular dynamics (ReaxFF-MD) and transition state theory (TST).

    The good ventilation of switchgear and transformer rooms | EEP· Ultimately, economic aspects such as procurement and operating expenses must be taken into account as well as the reliability (emergency power supply and redundancy) of the ventilation. At outside air temperatures of up to 30 °C, natural ventilation is generally sufficient.At higher temperatures there is danger that the permissible temperature for the equipment may be exceeded.
