IEC60112 Tracking Index Tester

Description The Tracking Index Tester is designed according to the IEC60112 standard. Model TI-1

Tracking Index Test Apparatus

1. Introduction

The tracking index test is an accelerated experiment to simulate the conductive substances deposited on the surface of the solid insulating material of household appliances, and assess if conducting paths formed gradually will cause the creepage on the surface of insulating materials, breakdown short circuit and fire hazard

The tracking index test apparatus is a equipment designed to conduct the tracking index testing, and can meet the test requirements of   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.

This equipment is controlled by single chip and push buttons. The test apparatus is built-in air exhaust, 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.
