High Voltage Tracking Resistance (HVTR)
UL 746A - National Technical Systems (NTS)
The High Voltage Tracking Resistance (HVTR) test method is used to assess the susceptibility to tracking of insulating materials that are exposed to high voltages outdoors. Insulators installed in the open are often at the mercy of humidity. Their electrical insulation properties can deteriorate to such an extent as a result that tracking paths are formed on the insulator surface. This test determines the tracking resistance that defines the dielectric strength of the insulating material surface and the maximum allowable leakage current (tracking).

Materials Testing
The importance of materials testing cannot be underestimated. Across every major industry, manufacturers, developers and operators of critically important systems, products and components need to be assured that the materials employed in forming their equipment are up to their intended tasks. That’s why the most diligent method of verifying that the materials companies use in manufacturing processes will perform to expectations and adhere to all applicable regulations is through reliable materials testing.
