What is a tracking test chamber，Let’s Analyze Leakage Tracing Test Apparatus

Solid insulation materials may form some conductive paths under the joint action of electric field and electrolyte, that is, leakage discharge traces may occur, and the resistance to leakage discharge traces is used to measure the insulation material’s ability to resist leakage discharge traces. Therefore, resistance to leakage discharge traces is an important index for measuring insulation.

Working Principle of leakage tracing test apparatus:

The leakage tracing test apparatus system uses the related characteristics of electric field strength and current scale between electric potential difference signals and insulation surface, discharge state and the degree of wetting and contamination of the insulation surface to detect leakage discharge traces. First, the system builds an electric field. When there are leakage discharge traces on the surface, the system can detect the attenuation of the electric field strength and the change of electric potential difference signals, thus achieving the detection of leakage discharge traces.

The leakage discharge traces tester applies frequency voltage (100-600V) to the sample surface and drops NH4Cl solution (20.0-23.0 mm3, 395 ± 5Ω·cm) at a height of 30-40 mm between the two electrodes to perform the leakage discharge traces test. This test can assess the wet surface discharge performance of solid insulation materials by applying the voltage level and the electric erosion depth value of the sample surface, and thus measure the CTI (Comparative Tracking Index) and PTI (Protective Tracking Index) of leakage discharge traces.

What is a tracking test chamber?

The tracking test chamber is a special testing instrument for determining the CTI and PTI of solid insulation materials and household electrical appliances according to relevant standards. It has the characteristics of simple, accurate, reliable and practical, and can simulate the environment under wet conditions. The main advantage of the Leakage Discharge Traces Tester is that it can accurately measure the CTI and PTI of tracking test chamber, thus realizing the quality inspection and certification of solid insulation materials or household electrical appliances.

Leakage Tracing Test Apparatus: Simulate the safety test of household electrical appliance products in actual use
The Leakage Tracing Test Apparatus is an equipment for testing of the safety of household electrical appliance products, aiming to simulate the inspection of the product’s use safety in the real environment. It tests whether there is leakage, electric shock, short circuit and fire caused by leakage, etc. Under the influence of pollution and humidity in the actual use environment, insulation materials may form leakage, which may damage the performance of insulation materials. In order to inspect the safety of household electrical appliance products in detail, the standard has made the specification of leakage tracing test apparatus, which can quickly test the extreme conditions by simulating, identify the anti-leakage discharge traces capacity of insulation materials, and Examiner’s Quality Approve the use safety of the product in harsh conditions.

When using the leakage tracing test apparatus, its equipment certificate must be valid, and the power must be ensured to be connected to a special socket with a ground wire to ensure reliable grounding. Attention should also be paid to personal protection to avoid injuries from leakage or contamination of the mouth, eyes and other parts by the solution. When using the leakage tracing test apparatus, the equipment certificate should be checked regularly to ensure that the fan is turned on to remove the smoke before the door is opened for operation, so as to ensure personal safety.

The use of leakage tracing test apparatus is increasingly valued in industries such as power, electronics, medical equipment, etc. It can help enterprises to evaluate the safety of electrical equipment, conduct quality control, improve the quality of equipment maintenance, and meet relevant regulations. The leakage tracing test apparatus plays an important role in the safety and quality assurance of electrical equipment, and has the advantages of guaranteeing the safety of equipment, improving product quality, extending the life of equipment, and meeting relevant regulatory requirements.
