TRANSFORMER HEALTH MONITORING SYSTEM

Keerthan Reddy G K , Abdul Razak H S

Abstract


Power transformer is a complex and critical component of the power transmission and distribution system. System abnormalities, loading, switching and ambient condition normally contributes towards accelerated aging and sudden failure. In the absence of critical components monitoring, the failure risk is always high. For early fault detection and real-time condition assessment, online monitoring system in accordance with age and conditions of the asset would be an important tool. After being indicative of abnormality, it is important to carry out offline tests/ diagnostics to ascertain the overall integrity and assessment to avoid unscheduled outages, financial/ revenue losses and environmental/ collateral damages. Paying higher attention to vital equipment Transformers are valuable components in electrical power networks Outages have not only financial repercussions, they also impact on the stability of the grid.


Keywords
