شکست بوشینگ - روند تحقیق و یافته ها

All the OIP bushings were supplied in the same patch filled with the same oil and operated in identical service conditions so degradation of insulation as chemical process can be considered in similar state. Electrically all bushings were subjected to identical voltage and load related stresses as transformers are operated in parallel. Thus combinations of these two factors are considered as causal factor for frequent breakdown of multiple bushings.
