IEC60587 High Voltage Tracking Index Tester ASTM D2303
High polymer high voltage leakage tracking, resistance to tracking:
Silicone products have good electrical insulation properties. Their
dielectric loss, voltage resistance, arc resistance, corona
resistance, volume resistivity and surface resistivity are among
the best in insulating materials, and their electrical properties
are affected by temperature and frequency. The impact is very
small. Therefore, they are a kind of stable electrical insulating
materials, which are widely used in the electronics and electrical
industries.
In addition to excellent heat resistance, silicone also has
excellent water repellency, which is a guarantee for high
reliability of electrical equipment used in wet conditions. The
high-voltage tracking tester produced by Dongguan Daxian Instrument
is a testing equipment developed and designed for the electrical
insulation performance, tracking resistance and corrosion
resistance of silicone products.

Test method:
| The constant tracking voltage method | the constant tracking voltage is the highest voltage at which 5 samples are not damaged after 6 hours |
| The step-by-step voltage tracking method | the step-by-step tracking voltage is the highest voltage that the five samples are not damaged after being subjected to Ih. |
Instructions for use:
Note: Use a new filter paper liner for each test.
First, pour the contaminated liquid into the filter paper liner to make the filter paper fully wet. Adjust the flow rate of the contaminated liquid and correct the flow rate as specified in Table 1. Observe the flow for at least 10 minutes to ensure that the contaminated liquid flows stably on the surface of the sample between the two electrodes. The contaminated liquid should flow from the shaft hole of the upper electrode and not overflow from the side or top of the filter paper.
Preparation of the sample:
Process the sample into a sheet, preferably 6mm in thickness,
50×120mm in size, drilled with electrode mounting holes, and make a
reference mark line at 45mm from the lower edge of the sample, and
clean the sample with distilled or deionized water , Make the
surface without any dirt, if the sample surface is smooth, it
should be slightly polished;
Preparation of filter paper liner:
Use the equipped knife to cut the filter paper into the shape shown in Figure 4, and pad the cut filter paper between the upper electrode and the sample. If you use a thicker filter paper, you usually need to pad 3 to 5 layers.
