Abstract

To apply dissolved gas analysis (DGA) for ester insulating oils, the gas generation characteristics of various ester insulating oils were studied under the partial discharges (PDs) and arc discharges. The test vessel was made for qualification of dissolved gas, and both PD and arc energy measuring devices were developed to estimate the discharge energy. The oil samples containing the dissolved gases were sampled and compared with before and after the discharge test, namely, these samples were analyzed by gas chromatograph. The analysis revealed the type and amount of dissolved gases caused by the discharges. In the paper, new diagnosis methods based on DGA are proposed to find abnormal conditions such as PDs and arc discharges in ester oil filled transformers.
