Tracking test apparatus is a special testing instrument in laboratory. The Tracking test apparatus is used to evaluate the resistance of solid insulating material surface to leakage mark under electric field and contaminated medium. It is suitable for lighting equipment, low-voltage electrical appliances, household appliances, machine tools, electrical motors, electric tools, electronic instruments, electrical instruments, information technology equipment research, production and quality inspection department. Comparative tracking Index test apparatus is also suitable for insulation material engineering plastic electrical accessories industry.
The IEC 60112 standard outlines the requirements for the determination of tracking resistance of insulating materials used in electrical and electronic equipment. This performance testing requires the use of a specialized tracking test apparatus that can accurately measure the electrical breakdown of the material under specific conditions. The tracking resistance of the insulation material is determined by the formation of a conducting path between the two electrodes. This apparatus is critical in ensuring that the insulation materials used in electrical and electronic equipment meet the required safety standards and can perform effectively under expected operating conditions.
The Tracking test apparatus is on a solid insulating material’s surface, Between specified size (2mm × 5mm ) platinum electrodes. Apply a certain voltage and time it 30 seconds and 35mm height, A conductive liquid (0.1% NH 4 CL) that drops the specified droplet volume,
Working Principle
Comparative tracking test apparatus is used to evaluate the leakage resistance of solid insulation surface under the combined action of electric field and wet or polluted medium, and to measure the electric trace index (CT1) and electric trace index (PT1).

The comparative tracking Index or CTI is used to judge the index of electrical trace relative to insulation material, and comply DIN EN 60112 with test standard. The CTI simulates tracking the current of the drops of liquid between two electrodes. Insulation materials commonly used may be exposed to moisture or dust, If conducted, it may cause the risk of stress or fire. This part satisfies DIN EN 60 112 / IEC 60 112 / or VDE 0303 part 1. Test meets KA method (The amount of falling material/Crawler tunnel depth) and KA method (Until the voltage of the 50th drop). CTI and PT1 values will be determined. Combination allows for fine-tuning of test voltage, test current, switching time, drop size and number of drops.
The case of electric leakage tracking test apparatus is made of 1.2 mm mirror stainless steel, Surface coating.
Equipment Features
The machine has the function of draining liquid, which is convenient for testing the air in the front air pipe.
Product accessories contain precision electronic scale to verify the electrode head on the sample force.
Tracking test apparatus use Omron relay, YOTO timer, melange geran leakage protection and other well-known brands to ensure the long-term trouble-free operation of equipment.
Lighting lamps and lanterns using standard explosion-proof lamps, in line with safety standards.
The Posano sealed exhaust fan is adopted to ensure the sealing of the box. And strong exhaust effect.
Imported solenoid valve is used to control the droplet size accurately, no need to adjust.
Use precise leakage ammeter to quickly determine the leakage current size of products (ensure the accuracy of CTI index)
Tracking index test apparatus can precisely adjust the height of the sample table and the position of the two electrodes, so as to facilitate the test.
Rectangular platinum electrodes were used, and the force of the two poles on the sample is 1.0N±0.05N. The applied voltage is adjustable between 100 ~ 600V(48 ~ 60Hz), When the short-circuit current is 1.0±0.1A, the voltage drop should not exceed 10%.
When the short-circuit leakage current in the test circuit is equal to or greater than 0.5A, Time maintain 2 seconds, relay action, cut off current, indicating unqualified test. The time constant of the drip device is adjustable, and the amount of drip is 44~50 drops/cm3 and the time interval of dripping is 30±5 seconds.
Comparative tracking Index tester (CTI Tester) Realized according to the standard: IEC 60112: 2009, GB4207 and other standards. The Tracking index tester is suitable for measuring the creepage index and the creepage resistance index of solid insulation material and its products of electrical and electronic products under damp conditions. The tracking test apparatus 600V IEC 60884 testing machine is simple, accurate, reliable and practical.

If the circuit current is greater than 0.5A and maintained for 2 seconds, the relay will cut off the current, indicating that the sample is unqualified.
During the operation of the tracking test apparatus, personnel should pay attention to personal protection to avoid the leakage injury or being contaminated by the solution to the mouth and eyes.
Do not open the door of the warehouse when the sample is tested. After the test or when the test fails and smoke is produced, first turn on the fan to remove the smoke, and then open the door of the warehouse for operation.
Before the experiment, it is necessary to confirm whether the CTI testing is within the valid period of measurement, otherwise, the experiment cannot be carried out.
Power supply application has the ground three pole socket, guarantees the grounding reliable. The exhaust pipe should go out of the window.
