Overview
The Beiguang Precision BDJC-10KV Dielectric Breakdown Strength Tester is an engineered solution for determining the electrical insulation integrity of solid, liquid, powder, and irregularly shaped dielectric materials under controlled AC and DC voltage stress. Based on the principle of controlled voltage ramping until dielectric failure occurs—measured as the instantaneous breakdown voltage—the instrument delivers repeatable, traceable, and standards-compliant results essential for R&D laboratories, quality control departments, and regulatory compliance testing in polymer, rubber, composite, and electrical insulation manufacturing. The system employs a high-stability, contactless solid-state voltage regulation architecture—eliminating mechanical variacs—to ensure linear, jitter-free voltage rise profiles critical for accurate comparative analysis across material batches and formulations. Designed for operation in ambient air or insulating oil media, the BDJC-10KV supports both short-duration impulse-like tests and extended-duration dielectric withstand evaluation per IEC 60243-1 and ASTM D149 methodologies.
Key Features
- True dual-mode AC/DC output with seamless switching via internal silicon stack configuration—no external rectifier modules required.
- Programmable voltage ramp rates from 0.1 to 5.0 kV/s, enabling precise alignment with test standard requirements (e.g., 0.5 kV/s for ASTM D149, 1.0 kV/s for GB/T 1408.1).
- Real-time current monitoring at 0.1 mA resolution with automatic circuit interruption within 50 ms of breakdown detection.
- Integrated oil bath chamber (removable per user specification) for standardized immersion testing per ASTM D877 and IEC 60156 protocols.
- Embedded Siemens industrial-grade CPU controller paired with PC-based software for deterministic data acquisition at up to 3 MB/s via USB 2.0—ensuring zero-latency synchronization between voltage ramping and current sampling.
- Multi-layer safety architecture including interlocked test chamber door cutoff, overcurrent/overvoltage/loss-of-phase protection, and automatic DC discharge alarm with integrated grounding rod.
- Full digital calibration traceability: supplied with NIM (National Institute of Metrology, China)-certified calibration certificate; optional UKAS or A2LA-accredited third-party certification available upon request.
Sample Compatibility & Compliance
The BDJC-10KV accommodates flat-sheet specimens (e.g., films, laminates), molded discs (ASTM D149 Type A electrodes), liquids (via ASTM D877-compliant electrode cups), powders (compressed pellet method), and irregular geometries using custom electrode fixtures. Electrode configurations comply with IEC 60243-1 (spherical, cylindrical, and needle-plane) and support electrode gap adjustment from 1 mm to 5 mm. All test procedures adhere to internationally recognized electrical safety and measurement standards—including GB/T 1408.1–2016 (equivalent to IEC 60243-1), ASTM D149, GB/T 1695–2005, and HG/T 3330—and are fully compatible with GLP/GMP documentation workflows. Data audit trails, user access controls, and electronic signature support align with FDA 21 CFR Part 11 requirements when configured with password-protected operator roles and encrypted result storage.
Software & Data Management
The proprietary Beiguang TestSuite™ software provides full instrument control, real-time curve visualization (voltage vs. time, current vs. time), and post-test analytical tools. Each test generates a color-coded breakdown curve overlaid with prior runs for repeatability assessment. Users may annotate, filter, and export raw datasets in CSV or XML formats compliant with LIMS integration. Software features include: configurable pass/fail thresholds, automatic report generation (PDF/Excel), multi-user role management with individual password protection, parameter versioning, and secure local database storage with timestamped metadata (operator ID, environmental conditions, calibration status). All data modifications are logged with immutable audit trail entries, satisfying ISO/IEC 17025 clause 7.9 and internal QA documentation mandates.
Applications
This tester serves core applications across academic research, industrial QC, and regulatory submission preparation—including but not limited to: evaluation of polymeric insulators for power transmission components; qualification of encapsulation resins used in EV battery modules; validation of dielectric coatings for medical device substrates; screening of nanocomposite fillers (e.g., SiO₂, Al₂O₃) in epoxy matrices; and comparative assessment of biodegradable polymer films for packaging electronics. It is routinely deployed by national laboratories (e.g., Chinese Academy of Sciences institutes), tier-1 automotive suppliers, aerospace composites manufacturers, and ISO 17025-accredited testing service providers to generate data referenced in UL 746, IEC 60674, and IEEE Std 930 reliability models.
FAQ
What is the maximum measurable breakdown voltage?
The BDJC-10KV is rated for continuous operation up to 10 kV AC/DC; however, it is validated for transient breakdown events up to 20 kV during calibration verification—ensuring margin for sensor linearity and safety headroom.
Can the system perform both AC and DC tests without hardware reconfiguration?
Yes—AC/DC mode selection is managed entirely through software command and internal shorting-bar actuation inside the high-voltage transformer tower; no manual wiring changes are required.
Is remote operation supported for hazardous-area testing?
Yes—wireless Bluetooth 5.0 and optional Ethernet connectivity enable full instrument control from ≥10 m distance, supporting human-machine separation in high-voltage labs per IEC 61010-1 Clause 6.4.2.
How is calibration traceability maintained?
Each unit ships with a NIM-certified calibration certificate covering voltage output, current sensing, and timing accuracy; annual recalibration services include full uncertainty budget reporting per ISO/IEC 17025 Annex A.
Does the software support automated compliance reporting for ISO/IEC 17025?
Yes—audit logs, electronic signatures, revision-controlled test templates, and raw data archiving meet all mandatory recordkeeping clauses in ISO/IEC 17025:2017 Section 7.5 and 7.9.
