Electrical insulation have played an important role in the electrical distribution industry more than 100 years ago. With evolution in use starting with the air and porcelain or glass insulators for the overhead electrical systems, insulating oil in electrical transformers, insulating gas in switchgear and solid insulation for various cables. Such a insulation that have been used since the past is necessary to be developed, improved, and changed to reduce the impact on the environment.
Nowadays many countries have announced for the carbon neutrality policy and plan to stop using green house gases in electrical equipment leads the manufacturers of electrical equipment to develop and introduce the green insulation to reduce the global warming from the destruction of the atmosphere causing and the increasing of the amount of carbon dioxide.
Therefore, the Provincial Electricity Authority (PEA) has a policy and strategy to aim for carbon neutrality and sustainability. Then it is necessary to have a plan and idea to improve, change and implement new electrical insulation technology used in various important electrical equipment, including solid insulation, liquid insulation, and gas insulation, which is considered a great challenge.
Because of high price of the new equipment with green insulation technology in the beginning, PEA has to consider carefully to select the appropriate new insulation both for new construction and replacement projects with evaluating among investment cost increasing, work processes changing, skill of workers improvement, and new tool adaptation to operate and maintain them to cover their life cycle according to the concept of asset management to be valuable and achieve the business goal.
