Tracking Index Test Device
1. Introduction of tracking index test device
The tracking index test device is applicable for research, production and quality inspection departments of lighting equipment, low-voltage electrical appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, and etc.. It is also suitable for insulating materials and engineering plastics, electrical connectors and auxiliary parts industry. The tracking index test device is made according to DIN EN60112, IEC60112, UL746A, ASTM D 3638-92, GB4706.1, GB/T4207 etc. Standard.
2. Test Principle of tracking index test device:
The tracking test is to apply a certain voltage between the 2mm*5mm platinum electrodes on the surface of a solid insulating material, and drop a conductive liquid (0.1% NH 4CL)with a specified droplet volume at a fixed height (35mm) for 30s to evaluate the leakage resistance of the surface of solid insulating materials under the combined action of electric field and humid or polluted media, and determine its comparative tracking index (CTI) and resistance to tracking index (PTI).
