Characteristics investigation of R407C in high voltage applications as an alternative to SF6

Results in Engineering
The concept of life without electrical power is not possible. All the industrial, domestic zones etc., requires power to operate, which is transmitted by means of overhead high voltage transmission lines from generating stations to sub-stations.
