  Environmental and Maintenance Benefits Conventional oil-immersed transformers pose environmental risks due to potential oil leakage and fire hazards. Power electronic transformers overcome these challenges through dry-type structures incorporating a high frequency transformer core. A high isolation transformer eliminates the need for insulating oil, reducing environmental impact and simplifying maintenance. Air cooling systems are often sufficient due to improved efficiency and reduced thermal losses. For high-voltage conversion, the use of a high frequency high voltage transformer ensures stable performance without the drawbacks of traditional insulation materials. Maintenance requirements are lower, and operational safety is improved. These environmental and operational benefits make PET technology highly suitable for urban installations, renewable energy projects, and industrial power systems seeking sustainable solutions.
