| Abstract: | First, through the exhaustive resereh, the factors influenced op rising hon of the oil - filledinstrument transformers are emumerated, the togic relations are found, the Relation Trees and theirsimplified be are constmcted. Then, accoording to the conditions in store of the oil - filled instrumenttransformers the true cause of tgδ rising again is foun using the elimination method. |
