The invention discloses a test method for a moisture intrusion point of an oil-immersed high pressure bushing. External insulation of the oil-immersed high pressure bushing is damaged due to defect ofproduction technology or improper installation and moisture in the environment intrudes the bushing via the damaged position continuously, but a dielectric loss tangent value and a capacitance of thebushing at present can only be used to evaluate the total moisture state of internal insulation of the bushing, and the moisture intrusion point of the bushing cannot be determined. According to thetest method of the invention, parameters of a hidden Markov model in different moisture intrusion points, moisture concentrations and temperatures are obtained, the probabilities of different moistureintrusion points of the bushing are calculated via a shuffled frog leaping algorithm according to a frequency-domain dielectric spectrum curve of test, and the moisture intrusion point of the oil-immersed high pressure bushing can be tested effectively.
