2013/3/20The working of SF6 CB of first generation was quite simple and it is some extent similar to air blast circuit breaker.Here SF6 gas was compressed and stored in a high pressure reservoir. During operation of SF6 circuit breaker, this highly compressed gas is released through the arc in the breaker and collected to a relatively low pressure reservoir and then it is pumped back to the high

In 1953, William James Scott showed that microbial growth in food is governed not by water content, as most people thought, but by water activity. Four years later, he established the concept of a minimum water activity for microbial growth. Water activity is now routinely used by food manufacturers to

2020/10/15Luckily, leakage rates are low and accidents extremely rare. The sheer amount of SF 6 used in the medium voltage (MV) and high voltage (HV) sectors nevertheless raises environmental concerns . This is especially the case as ongoing network extensions and the integration of renewable energy installations are increasing the banked SF 6 volume.

Sulfur hexafluoride is a highly chemically inert gas with several important industrial applications. It is stable against fused alkali, oxygen and ammonia, even at several hundred degrees Celsius. In this work, the reactions between metals (Li–Cs, Sr, Ba, Eu, Yb) dissolved in liquid ammonia and SF6 are reported, leading to mono or bivalent fluorides and sulfides. To this end, SF6 was passed
