Fault Analysis and Condition Monitoring of Transformer

The unscheduled outages of transformers, due to unexpected failures are creating more problems for load management and system stability. Condition monitoring is done on power transformer those monitor various parameters predict fault accruing possibility and reduced unscheduled outage. In this paper, different condition monitoring techniques have discussed. The transformer model is prepared with healthy and faulty conditions using MATLAB Simulink. L-G, L-L-G, and L-L-L-G fault have been discussed in this paper. Various parameters are used for condition monitoring and fault diagnosis.
