From the view of operation reliability, it is necessary for operator s to provide a monitoring of transformer's failure free operation. The application of monitoring system enables to warn ti mely of the rising failure and also decrease of degradation of single subsystems of machine. When failure is detected, it is important to support this detection by other measurements tha t would lead to exact determination of the failure. SFRA analysis (Sweep Frequency Response Analysis) is such additional method in our monitoring.
