This paper, discusses the dielectric on-line monitoring of a high-voltage capacitive equipment .The main difficulty of the dielectric monitoring and diagnosis technology is the measurement of the dielectric phase angle of the equipment. A sampling method is proposed to pick up the fundamental wave of the signal precisely. A new calculation method of dielectric loss based on ANN is introduced in detail. A WEB-dielectric information inquiry system is presented based on the B/S mode.
