The National Energy Technology Center (ENTEC), under the National Science and Technology Development Agency (NSTDA), in collaboration with the Metropolitan Electricity Authority (MEA), has launched a pilot implementation of “EnPAT,” a safe transformer oil derived from Thai palm oil, in Bangkok. The installation took place in Khlong Song Ton Nun Subdistrict, Lat Krabang District, under the supervision of MEA Lat Krabang, deploying transformers filled with EnPAT and integrated with an online monitoring system to ensure real-time performance tracking. The installation was overseen by Mr. Chuangchot Chawawit, Assistant Director of MEA Lat Krabang, and Mr. Sunan Sing-in, Assistant Director of the Distribution Services Division.
EnPAT transformer oil features flash point and fire point that are twice as high as those of conventional mineral transformer oil, significantly enhancing operational safety. EnPAT is also biodegradable and environmentally friendly, posing no contamination risks in the event of leaks. Moreover, it can be recycled as feedstock for biodiesel production. Notably, over 97% of its raw materials are sourced domestically from Thai palm oil, helping to add value and strengthen the economic stability of Thai farmers.
This pilot installation marks a first step in using EnPAT within MEA’s power distribution system, aiming to enhance the safety of electricity distribution networks, especially in densely populated urban areas under MEA’s responsibility. The adoption of EnPAT represents a proactive measure to ensure both safety and environmental sustainability. Following the installation, MEA and the NSTDA research team will continue to monitor and analyze the performance data of the EnPAT-fill transformers to evaluate their ongoing operational efficiency.
