The Study Of Transformer Insulation Testing Under Working Voltage

The testing on-line of electric power facilities is a important technical method which can ensure the safety of power suppy. The article focuses on the testing of transformer insulationg testing' insulation, discussing the importance of transformer insulation testing under working voltage.First,ittells us how to choose the testing parameter, how to establish the mathematic model, how to choose the testing signal.second, it gives us a method, of signal traasmission and anti-jamming.Third,it gives us an example of transfomer insulation testing on-line.The article proves that with the support of computer system , the study of of insalation testing on-line will have a good fature.
