The invention discloses a high voltage insulator equivalent salt density optical fiber test method based on a particle swarm support vector machine. In the method, firstly luminous flux attenuation and relative humidity are tested to be transmitted to a supervisory computer in a manner of wireless communication; then the luminous flux attenuation is subject to normalization pretreatment; referringto a standard relation curve graph of dust ratio with the luminous flux attenuation and the relative humidity, corresponding dust ratio is searched; and the particle swarm support vector machine is used for establishing a nonlinearity regression model among an insulator equivalent salt density value, the luminous flux attenuation, the relative humidity, and the dust ratio to obtain the insulatorequivalent salt density value. The high voltage insulator equivalent salt density optical fiber test method based on the particle swarm support vector machine in the invention realizes on-line test ofinsulator salt density with high precision, is suitable for various voltage levels, avoids the defects of the traditional salt density measurement such as time consuming, effort consuming and poor measurement effect, and improves reliability of power supply system.
