The high-voltage trace tester is a simulated test item specified in standards such as GB/T653-2014/IEC60587-2007 "Test Method for Evaluating the Resistance of Electrical Insulation Materials to Trace and Corrosion under Harsh Environmental Conditions".

The high-voltage trace tester is suitable for testing the electrical and electronic products, household appliances, and their materials for resistance to electrical traces and corrosion, simulating at power frequency（48Hz - 62Hz）Next, evaluate the electrical insulation material's resistance to electrical traces and corrosion under harsh environmental conditions by measuring its resistance to electrical traces and corrosion using liquid pollutants and inclined surface samples. Under the influence of humidity and impurities in electrical products, insulation leakage may occur between charged parts of different polarities or between charged parts and grounded metals, resulting in electric arcs that can cause breakdown and short circuits in electrical appliances or material erosion due to discharge, and even ignite and cause fires. This tester is a destructive test conducted on insulation materials to simulate the above situation. It is used to measure and evaluate the relative resistance of insulators to leakage and tracing under the action of electric fields and impurity water at a specified voltage. It is suitable for solid electrical insulation materials and products of electrical and electronic products, household appliances, such as relay sockets, transfer switch covers, contactors, etc.

Introduction to parameters of high-voltage trace tester:

Product Features:

1：Sample size:This instrument supports both5 sets of samples are tested simultaneously, each with an independent control system for control

2: Operation display:instrument controlEasy to operate, intuitive data display, able to display the real-time leakage current of each sample, the maximum current value from the beginning of the experiment to this point, and the real-time voltage value of each sample in real time.

3：Alarm prompt:leakage currentThe range of 0mA to 100mA can be freely set. When a certain test current exceeds the set current value during the experiment, it can prompt an alarm and cut off the high-voltage power supply of that circuit, without affecting other samples to continue the test

4：Droplet control:The droplet flow rate is controlled by a peristaltic pump; Flow rate of peristaltic pumpSet freely according to actual needs.

5：Liquid recovery:The tank for holding the test liquid in this device is separate from the liquid used in the test. Ensure the accuracy of the test liquid.

6：Time record:The real-time recording of the time for each experiment in this device is in minutes.

7：Automatic voltage boost:Set the test voltage and automatically raise it to the specified voltage.

8：Automatic zeroing:After the experiment is completed, the voltage automatically returns to zero position

9：Test time:Can independently set the test time

10：Exhaust system:A ventilation system with independent exhaust can effectively remove harmful gases generated during the testing process from the outside,.

11: Lighting system:This instrument is equipped with an independent lighting system, which can be turned on when observing internal test conditions and external light brightness is insufficient.

12: Voltage stability:The high voltage of this device is regulated by an autotransformer and supplied to a fixed ratio oil immersed transformer to generate high voltage. Due to the fixed capacity of oil in oil immersed transformers, it can be ensured that the voltage drop during the experiment at a fixed voltage is very low.

13：Data calibration:Long term use of the device can cause changes in voltage and current, and this device can calibrate voltage and current.

14：Test voltage:DC voltage, AC voltage (optional)

15：Test method:Constant voltage method, stepwise voltage method

End of experiment:

1：Pour out the contaminated liquid after passing through the electrode and clean the liquid tank

2: Lift the silicone tube on the peristaltic pump and apply pressure to it for a long time, causing a decrease in the lifespan of the silicone tube.

3：Remove the sample and electrode, observe the sample and clean the electrode. It is recommended to clean the electrode with anhydrous alcohol. If conditions permit, the electrode can be replaced every time the experiment is conducted
