Fault Diagnosis is based on expert knowledge base, posed by experts’ experiences. Latent Fault Diagnostic (LFD) and Insulation Precautionary Test (IPT) are popularly used in reality ,so as to diagnose faults of transformers’ insulation. LFD, is used to indicate the latent faults of transformers, based on Dissolved Gas Analysis (DGA), and assisted by External Examination (EE), Insulation Oil (IO).IPT, consisted of Insulation Resistance ,Ohmic Resistance, Oil Dielectric Loss ,DC leaking Current and Bushing. Through LFD and ITP, TFDES can judge synthetically the whole insulation level of transformer, and give out proper expert suggestions to operators. This TFDES , pleted through a lot of investigation and researching, affiliated with Test Report and some other functions, thinking pletely of onthespot need, is very worthy practically.Key System。 Faults Diagnosis。 Database。 Knowledge Base目錄1２ 電力變壓器絕緣缺點診斷模型 .................................... 5. 電力變壓器構造簡介 ........................................... 5. 電力變壓器絕緣根本知識 ....................................... 5 ........................................... 5 ................................... 6. 電力變壓器的缺點及檢測手段 ................................... 7 缺點緣故及其品種 ....................................
