In high voltage transformer bushings, insulation works by preventing electrical discharges between the high voltage conductor and the grounded transformer tank. The insulation is typically made of materials like porcelain or resin-impregnated paper (RIP) and is designed to withstand high electrical stresses while minimizing leakage currents. The oil or gas within the bushing provides additional insulation and cooling to prevent overheating and failure.
