Comparison of the dielectric performance of polluted composite insulators under AC and DC stress using the rapid flash over method

Being in the middle of the transition from a centralized generation, top-down oriented grid to a decentralized power generation grid with bulk transmission overlay, DC transmission becomes an important factor. This is resulting in a mixture of aged and new AC, and upcoming DC components. Additionally, the growing number of assets increases the complexity of asset health management, further raising the workload of asset managers.
