Automated Dielectric Breakdown Test Set for Insulating Materials (D149)

Overview

Automated Dielectric Breakdown Test Set for Insulating Materials (D149) is an automated high-voltage test system configured for dielectric breakdown testing of insulating materials (D149). Standard output voltages are provided up to 100 kV AC and DC and the product line includes both AC- and DC-capable configurations and combinations. The control package is identified as the 600C SERIES CONTROLS with a display accuracy of ±0.8% of reading + 0.2% of range +LSD. Over-current protection is user-adjustable with the over-current trip point configurable from 10% to 110% of rated output current. Model output capability examples (as configured): - 6CC50-2/D149: ≈0-50 kVAC, 40 mA and ≈0-5 kVAC, 100 mA - 6CC100-5/D149: ≈0-100 kVAC, 50 mA and ≈0-10 kVAC, 100 mA - 6CC20-0.8/D149: ≈0-20 kVAC, 40 mA and ≈0-3 kVAC, 100 mA - 6TC4100-10/50-2/D149: ≈0-50 kVAC, 40 mA and ≈0-100 kVDC, 10 mA - 4TC40-10/D149: ≈0-40 kVDC, 10 mA - 4TC100-10/D149: ≈0-100 kVDC, 10 mA The product family provides dual-range output options (higher-voltage/ lower-current and lower-voltage/ higher-current ranges) to accommodate different test specimen geometries and breakdown energy requirements. Typical use is automated, repeatable dielectric breakdown testing of insulating materials in laboratory and industrial quality-control environments where D149 test procedures are applied. The system supports AC and DC breakdown measurements up to 100 kV, letting users select model variants based on required maximum voltage and available test current for sample size and electrode configuration. Operators choose AC-focused models (6CC series) when high-voltage AC breakdown testing is required and DC-focused models (4TC series) or mixed AC/DC models (6TC4100-10/50-2/D149) when DC breakdown or both modes are needed. The adjustable over-current trip (10%–110% of rated current) and the 600C series display accuracy enable controlled ramping and reliable pass/fail decision-making during automated test sequences for production QA or R&D validation of insulating materials.
