Overview
The Beiguang Jingyi BGJY-50 Insulating Material Dielectric Breakdown Tester is a precision high-voltage test system engineered for determining the dielectric strength and breakdown voltage of solid and liquid insulating materials under AC and DC conditions. It operates on the principle of controlled voltage ramping—applying a continuously increasing electric field across a standardized test specimen until electrical breakdown occurs—thereby quantifying the material’s intrinsic resistance to electrical failure. Designed in strict compliance with international and national standards—including ASTM D149, IEC 60243-1, GB/T 1408.1–2016, GB/T 1695–2005, GB/T 3333, DL/T 429.9, and GB/T 507—the instrument delivers traceable, repeatable, and auditable results essential for quality control laboratories, R&D centers, and certification bodies serving power transmission, transformer manufacturing, cable production, and electrical equipment industries.
Key Features
- Full-range programmable output: 0–50 kV AC/DC, continuously adjustable with ±1% voltage accuracy (calibrated per ISO/IEC 17025-accredited procedures)
- Precision digital voltage ramp control: Adjustable rise rate from 0.01 kV/s to 5 kV/s, implemented via Siemens embedded CPU architecture with real-time closed-loop feedback
- Dual-mode testing capability: Supports uniform ramp, stepwise gradient, and sustained withstand voltage tests (0–7 h duration, software-defined)
- Multi-criteria breakdown detection: Simultaneous monitoring of leakage current (resolution: 0.01 mA) and voltage collapse, with dual-trigger logic (voltage threshold + current threshold)
- Integrated safety architecture: Triple-redundant protection including overvoltage cutoff (<50 ms response), overcurrent interruption (<0.05 s), interlocked safety door, zero-voltage reset, and automatic post-test discharge
- Wireless Bluetooth 5.0 + USB 2.0 + RS-232 dual-channel communication: Enables true human-machine separation; supports remote operation up to 30 m without latency (data throughput: up to 3 MB/s)
- Modular test chamber design: Includes optional oil bath fixture (ASTM-compliant electrode configuration) for liquid dielectric testing; air-gap testing per IEC 60243-1 Clause 6
Sample Compatibility & Compliance
The BGJY-50 accommodates standardized specimens per IEC 60243-1, ASTM D149, and GB/T 1408.1—including rigid sheets (e.g., pressboard, epoxy laminates), flexible films (polyimide, PET), molded resins, and liquids (transformer oil, silicone fluids). Electrode configurations comply with Type 1 (sphere-sphere), Type 2 (sphere-plane), and Type 3 (cylindrical) geometries as specified in IEC 60243-1 Annex A. All test sequences adhere to GLP-aligned data integrity requirements: audit-trail-enabled software logs operator ID, timestamp, parameter set, raw voltage/current waveforms, and pass/fail determinations. Optional NIST-traceable calibration certificate (CNAS-accredited lab) available upon request.
Software & Data Management
The proprietary PC-based control suite features role-based access control (multi-user login with password-protected profiles), configurable test templates, and automated report generation compliant with ISO 17025 documentation requirements. Real-time plotting displays voltage vs. time and leakage current vs. voltage curves synchronized at 10 kHz sampling. Data export supports CSV, PDF, and XML formats; comparative analysis allows overlay of ≥5 test curves with color-coded differentiation. Software enforces 21 CFR Part 11 readiness through electronic signatures, immutable audit trails, and user-action logging. Firmware updates are delivered via secure HTTPS channel; version history and change logs are retained indefinitely.
Applications
This tester serves critical functions across multiple sectors: verification of cellulose-based insulating pressboard used in high-voltage transformers (per IEEE C57.104); qualification of polymeric cable jacketing materials under accelerated aging protocols; evaluation of vacuum-potted encapsulants for aerospace electronics; routine QC of dielectric oils per ASTM D877 and D1816; and R&D validation of nanocomposite insulators. Its dual AC/DC capability supports both power-frequency (50/60 Hz) and HVDC insulation system development—particularly relevant for renewable energy grid interconnections and offshore wind converter stations.
FAQ
Does the BGJY-50 support both AC and DC breakdown testing?
Yes—it delivers fully independent AC (50/60 Hz) and DC outputs, each calibrated to ±1% full scale, with dedicated circuitry to prevent cross-mode interference.
Can test parameters be modified during an active test sequence?
No—parameter changes (e.g., ramp rate, hold time) require test suspension and reinitialization to maintain data integrity and regulatory compliance.
Is third-party calibration certification included with purchase?
A factory calibration report is standard; CNAS-accredited or NIST-traceable certificates are available as optional add-ons.
What safety certifications does the instrument carry?
The system meets IEC 61010-1:2010 (Measurement Category II, Pollution Degree 2) and incorporates redundant hardware interlocks validated per EN 60204-1.
How is data integrity ensured during long-duration withstand tests?
All analog inputs are isolated and digitized at 16-bit resolution; raw waveform buffers are stored locally on non-volatile memory prior to PC transfer, preventing loss during network interruption.
