Abstract
The present invention provides a method (100, 200) for obtaining failure prognostic information of electrical power equipment based on degradation of dielectric insulation fluid that is immersed in components of said power equipment that include electrical windings and tap-changers comprising a step (107) of computing a rate of change with respect to time of each of a plurality of sets of tertiary (106a, 106b, 106c) and secondary (105a, 105b, 105c) first order chromatic parameters obtained for a plurality of time instances and which have been grouped according to parameter type of insulation fluid degradation, such as "Dissolved Gas Analysis (DGA)", "Acidity, Water Content, Dielectric Strength (AWD)" and a step (108) of assigning scores to said plurality of sets of tertiary (106a, 106b, 106c) and secondary (105a. 105b, 105c) first order chromatic parameters at said plurality of time instances and the rate of change with respect to time of said sets of tertiary (106a, 106b, 106c) and secondary (105a, 105b, 105c) first order chromatic parameters.
