Development of the On-line Power Transformer State Monitoring System  
  Authors : Serhiy Denysiuk, Ivan Prytyskach


Creating an integrated energy system for efficient operation of power networks requires performing accurate monitoring of electrical equipment. According to current definitions, monitoring should include both automatic observation and assessment of the object state. In this article presented the concept of online monitoring system, which involves power transformers state assessment. Proposed to present the architecture of the system in the form of four levels performing certain functions. The information is given on the transformer physical characteristics models used to assess its condition.

The implementation of the continuous monitoring of the state of the transformer facilitates the preventive care for such equipment. Information about the actual state of the transformer allows making preventive measures to the appearance of specific defects in the transformer or to abnormal operating modes. This makes possible to increase the time between overhaul and reduce the number of diagnostic measures for transformer requiring disconnected.
