Application of Cole–Cole model to transformer oil-paper insulation considering distributed dielectric relaxation

Application of Cole–Cole model to transformer oil-paper insulation considering distributed dielectric relaxation

Researchers have been exploring dielectric testing techniques both in time and frequency domain for insulation condition assessment of oil-paper insulated transformers. In a practical dielectric system, dipoles are found to behave according to a distribution of elementary Debye relaxation properties...
