FAQ

(1) What is the Electronic Tracking Index Tester?

It is a precision instrument for determining the Comparative Tracking Index (CTI) and Proof Tracking Index (PTI) of solid insulating materials.

(2) What is this equipment used for?

It is used to evaluate electrical insulation resistance and surface tracking characteristics of plastics, ceramics, wires, cables, and polymer composites.

(3) What types are available?

Standard laboratory units with adjustable voltage and droplet control; optional configurations for higher voltage or multiple sample testing available.

(4) What industry problems can it solve?

Ensures insulation materials meet safety standards, prevents electrical failures due to tracking, and verifies material suitability for high-voltage applications.

(5) What is the difference between CTI and PTI testing?

CTI determines the maximum voltage level at which a material can resist tracking under specified conditions, while PTI verifies whether a material can withstand a defined voltage value. Both are important indicators for insulation safety evaluation.

(6) Why is electrolyte dripping used during the test?

Electrolyte droplets simulate contamination and moisture conditions that may create leakage paths on insulation surfaces. This helps evaluate the material’s ability to resist electrical tracking during actual service conditions.

(7) What should laboratories consider when purchasing a tracking index tester?

Selection should consider applicable standards, voltage range, electrode accuracy, droplet control stability, and safety design. For different testing requirements, QINSUN engineers can provide suitable equipment recommendations.

(8) Why is IEC 60112 widely used for insulation testing?

IEC 60112 provides a recognized test method for determining CTI and PTI values of solid insulating materials. These results are commonly used for material selection, electrical design, and safety assessment of electronic products.
