Partial Discharge Measurements in a High Voltage Gas Insulated Transmission Line Insulated with CO2 [PDF]

Energies, 2020
This paper uses practical experimentation to analyse the effect of replacing SF6 with pure CO2 in conventional gas insulated transmission line sections by studying partial discharge measurements taken with applied voltages up to 242 kV (rms). The results can also help in understanding the properties of new alternative gas mixtures which can be utilised

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.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
