The current application status of dry-type transformers

Dry type transformers do not require them to be placed in separate rooms due to the lack of oil, which means there are no issues such as fire, explosion, or pollution. Therefore, electrical codes and regulations do not require dry-type transformers to be placed in separate rooms. The loss and noise have been reduced to a new level, creating conditions for transformers and low-voltage panels to be placed in the same distribution room.
As an important equipment in the power system of offshore oil platforms, the safe and reliable operation of dry-type transformers is crucial for the operation of the power system. Dry type transformers are prone to insulation partial discharge and local overheating problems in humid salt spray marine environments. The application of an online monitoring system for dry-type transformers can effectively achieve online monitoring of transformer status and ensure the stable operation of the power system on offshore oil platforms.
