Test principle:
A conductive liquid (0.1% by weight) having a predetermined droplet volume was dropped onto the surface of the solid insulating material and a platinum electrode of a predetermined size (2 mm × 5 mm) by applying a voltage and dropping a predetermined height (35 mm) NH 4 CL) was used to evaluate the leakage resistance of the surface of the solid insulating material under the combined effect of electric field and moisture or contaminating medium. The relative electrical tracing index (CT1) and the resistance to tracing index (PT1)
