Lab IEC 60112 PTI And CTI Tracking Index Tester

Introduction:

The tracking index tester is a special testing instrument developed, designed and manufactured in strict accordance with GB 4207, IEC 60112, JIS C 2134 and other standards. It is suitable for research, production and quality inspection departments of lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, and is also suitable for insulating materials, engineering plastics, electrical connectors, and accessories industries. It simulates the determination of the tracking index and the resistance tracking index under humid conditions, and has the characteristics of simplicity, accuracy, reliability and practicality.

Tracking test is a test method used to evaluate the insulation performance of electrical equipment, IEC 60112. This test is used to detect whether the insulation materials of electrical and electronic products are prone to leakage and arcing (i.e. tracking) in humid environmental conditions.

Test principle:

It is used to evaluate the tolerance of the surface of solid insulating materials under the combined action of electric field and contaminated medium, and to determine its comparative tracking index (CTI) and proof tracking index (PTI);
Comparative Tracking Index (CTI): The highest voltage value that the surface of the insulating material can withstand 50 drops of electrolysis (0.1% ammonium chloride aqueous solution) without forming a leakage trace, in V.
Proof Tracking Index (PTI): The voltage required for the material surface to form a permanent conductive carbon path after withstanding the action of 50 drops of electrolyte at a rate of one drop per 30 seconds, expressed in V.
