Additional information

RT-727 High Voltage Tracking Tester

The RT-727 high-voltage tracking tester is suitable for anti-tracking and erosion testing of electronic products, household appliances, and other materials. It simulates frequencies (45 Hz- 65 Hz) or corresponding DC voltages, liquid pollutants, and slope samples through resistance tracking and erosion measurement to evaluate the resistance of electrical insulation materials to tracking and erosion under harsh environmental conditions.

Working Principle:

The electric trace resistance and corrosion tester consists of a control part and a high-voltage testing part. The instrument applies a power frequency voltage of (1000-6000) V to the surface of the sample between two electrodes. At different voltage levels, NH4CL test solution with deionized wetting agent and a resistivity of (395 ± 5) Ω· cm was flowed into the surface of the sample tilted forward at a 45 ° angle to the horizontal at flow rates of 0.075, 0.15, 0.30, 0.60, and 0.90 ml/min. When the test solution penetrates the surface of the sample between the upper and lower electrodes, the Joule heat generated by the current causes local drying of the sample surface, forming a dry zone. The dry zone generates a potential gradient on the surface of the sample, forming local micro luminescent discharge – spark discharge. Spark discharge causes local thermal decomposition of the sample surface, generating carbides that extend between the two electrodes and result in electric leakage and trace damage.

Operation Steps

RT-727 Operation Instructions

Firstly, select the sample that meets the test requirements and perform any necessary pre-treatment steps, such as cleaning and drying. Then, place the sample in the test chamber and set the appropriate parameters, such as temperature, humidity, and electric field strength, to initiate the accelerated aging test. During the experiment, it is necessary to regularly observe and record changes in the sample, such as surface tracking, corrosion, and color changes. When there is an obvious electric trace or corrosion on the sample, it is necessary to stop the test promptly and further analyze and evaluate the sample. The advantage of the IEC 60587 test method lies in its standardization and repeatability, which enable the objective evaluation of the resistance to electrical traces and corrosion of different insulation materials, providing an essential basis for the selection and design of electrical equipment. Meanwhile, this method can also simulate the environmental conditions during actual use, making the evaluation results more closely reflect the actual situation.
