PTI and CTI Tracking Index Test Apparatus

1. Introduction

The tracking index test apparatus is designed according to IEC60112, UL746A, GB.T4207, GB4706.1 and TMD 3628-92. On the surface of the solid insulating material, a certain voltage is applied between the platinum electrodes (2 mm × 5 mm) , and drops the pollution liquid (0.1% NH4CL) with specified droplet volume in fixed height (35mm) for 30s to evaluate the resistance of the surface of solid insulating materials under the combined action of electric field and contaminated medium, and its Comparative tracking index (CTI) and proof tracking index (PTI) are determined. Tracking index test apparatus is mainly used in the industries of lighting appliance, low voltage appliance, household appliance, motor, electronic appliance, instrument and etc. It is a good tool for research department, production department and QC department.


The tracking index test apparatus is controlled by single chip and push buttons. The test apparatus is built-in air exhaust, the exhaust fan automatically draws air when power on, and automatically run for 2 minutes when power off. The front panel is transparent for easy observation of the experimental process.


Proof Tracking Index (PTI): the voltage value of the material subjected to 50 drops of electrolyte without electrical tracking, the unit is volt.

Comparative Tracking Index (CTI): The highest voltage value at which the surface of the material can withstand 50 drops of electrolyte without forming electrical tracking, the unit is volt.

Test solutions: The preparation ratio is 1:1000, that is 0.1g of NH4CI with 100g (100ml) of distilled water
