Transformer oil oxidation retardation Proposed method comprises placing hollow truncated cone with hole at waveguide end top to place waveguide with hollow truncated cone in electric unit filled with transformer oil. Note here that ions flow down from surfaces of waveguide and hollow truncated cone to induce rotary magnetic field in ambient space. Free radicals in chaotic state come to rotary magnetic lines of force. Distance between free radicals decreases to make free radicals integrate into clusters for recombination of free radicals into neutral molecules. This results in decrease in concentration of free radicals in transformer oil. It brings about transformer oil oxidation retardation. |
