A method for assessing sliding electrical contact performance of an electric locomotive pantograph-catenary system includes determining a current manifestation of a catenary-following ability of a pantograph to a catenary of the pantograph-catenary system, wherein the current manifestation is one or more of a pressure difference, a time delay, and a curve difference; and performing comparison between a fluctuating pressure curve related to a fluctuating pressure of the catenary and a catenary-following pressure curve related to a catenary-following pressure of the pantograph over time under the current manifestation, and rating the catenary-following ability of the pantograph under the current manifestation according to a result of the comparison. By implementing the method, precise assessment of the sliding electrical contact performance can be achieved.
