Introduction to the Transformer Online Dryout System

Online drying of transformers is an innovative process that maintains the electrical properties of insulating oil while simultaneously drying the core of the transformer. It removes moisture from the oil and winding paper in a live transformer by continuously circulating the oil through a system without disturbing the Dissolved Gas Analysis (DGA).

CbS systems incorporate all the necessary features to allow a transformer to remain in service while effectively removing moisture from its insulation. The system is designed with robust safety mechanisms, including multiple alarm features that automatically shut it off and isolate it from the transformer in case of any abnormal signal.

Key Features

• Live Operation: Maintains transformer service while drying insulation.
• Safe Design: Equipped with alarm features for automatic shutdown and isolation in case of abnormal conditions.
• Non-Intrusive: No interruption to transformer operation or DGA profile.
• Cost-Effective: Provides a reliable and economical alternative to traditional heat and vacuum systems.
• Flexible: Once dried, transformers can have the system retrofitted for extended oil processing applications.
