Tracking Test Chamber | Leakage Tracking Test Apparatus
Leave a Message
The TTC-1 Tracking Test Chamber, also designated as the CTI PTI Tracking Flammability Test Chamber or Leakage Tracking Test Apparatus, performs standardized evaluation of tracking resistance in solid insulating materials under humid or contaminated environmental conditions. This apparatus simulates operational scenarios where surface contamination (including dust and moisture accumulation) induces leakage current across insulating components within electrical equipment, potentially leading to tracking corrosion or dielectric breakdown.
The test methodology involves controlled dripping of a standardized contaminating solution (0.1% ammonium chloride solution) onto the specimen surface while applying specified test voltages and monitoring resultant leakage currents. Sustained flame propagation or insulation breakdown determines the material’s Comparative Tracking Index (CTI) and Proof Tracking Index (PTI), providing critical data for insulation material selection and product safety design in electrical and electronic applications.
The TTC-1 Leakage Tracking Test Apparatus incorporates a high-precision voltage regulation and current monitoring system, maintaining applied voltage accuracy (100V~600V AC) within ±1% tolerance. The leakage current monitoring range spans 0~100mA, accommodating diverse material testing requirements. An automated dripping mechanism ensures precise dripping rate (30 drops/min ±5 drops/min) and volume control, eliminating operator-induced variability. Integrated flame detection with automatic power interruption provides safety protection during sustained combustion events, ensuring test integrity and data accuracy.
This equipment finds application in corporate research and development quality control, third-party testing laboratories, and certification body compliance verification.
