| Résumé : |
The voltage test of the comparative tracking index is limited to 600 V so far. In many areas the voltages increase, especially for electrical vehicles. Therefore, it is interesting to know what the real limits of isolating materials are. These are considerably higher. To test these, a modified test set-up is necessary.

- Standard measurement setup prevents tests
- High CTI thanks to glass fibers
- CTI measured according to IEC 60112
- Fig. 1 : The creepage distance, i.e. the shortest distance between two conductive parts along the surface is usually longer than the air gap, the shortest distance between two conductive parts
- Fig. 2 : At over 600V, the measurement setupprovided by the standard causes a short circuit through the air. For this reason, the electrodes were turned by 180° for the tests
- Table 1 : Different PLC-classes according to the failure voltage
- Table 2 : Overview of the Genestar types tested : three of them show no tracking even at 750V |
