Frequency domain spectroscopy is a potential tool for non-invasive condition assessment of oil-paper insulation in power equipment. On the other hand, it is well known that the results of frequency domain spectroscopy are affected predominantly by temperature. Moreover, the voltage used for frequency domain spectroscopy is sinusoidal is nature. But the actual insulation system at site is stressed...
Condition assessment of in-service power transformers are becoming increasingly important for maintaining reliable and uninterruptable power supply. Among non-invasive, modern condition assessment tools, frequency domain spectroscopy is predominant in determining the aging of oil-paper insulation in power transformers. However, the results of frequency domain spectroscopy are severely influenced by...
