“…CTI is correlated with the tendency of materials to carbonize [ 28 ]. However, there are few papers on CTI in the technical literature [ 105 ]. Some of them study the influence of pressure [ 54 , 81 ], temperature [ 91 ], and atmospheric conditions [ 106 ] for some polymeric materials.…”

“…According to IEC 60112 [ 24 ], the CTI is the most commonly used index to estimate the material’s sensitivity to surface tracking. The CTI value is determined from an accelerated test method [ 105 ], often conducted under contaminated conditions, where a voltage is applied between two electrodes placed on the surface of the material. The CTI indicates the tracking performance of insulation materials under wet and contaminated conditions.…”

With the increasing electrification of the transportation and mobility sectors, polymer insulation materials are inevitably exposed to harsher environments, including exposure to contamination, wide temperature ranges, operation at higher voltages and switching frequencies, and low-pressure environments. This paper reviews the tests to characterize the polymeric materials used in insulation systems for electric mobility applications, focusing on resistance to tracking. This paper also reports on the limitations of existing standard test methods and identifies the challenges and research needs to meet the increasing demands of the electric mobility industry. To this end, an evaluation of the scientific and technological state of the art is carried out through the analysis of theses, research articles, technical reports, manufacturers’ datasheets, international standards, and white papers.
