XHYY102S Insulating Oil Dielectric Strength Tester is a fully automatic, three-cup diagnostic instrument engineered for precise breakdown voltage (BDV) testing of insulating oils used in transformers, circuit breakers, and other oil-immersed electrical equipment. Independently developed and manufactured in strict accordance with national standard GB/T507-2002, industry standard DL429.9-91, and the latest power industry standard DL/T846.7-2004, this instrument employs a large-capacity single-chip microcontroller as its core, achieving full automation of the entire testing cycle. It delivers high measurement precision, significantly improves operational efficiency, and substantially reduces the labor intensity of field personnel.
Large-Capacity MCU Control — Single-chip microcontroller with wide-range watchdog circuit ensures stable, reliable operation and prevents system crashes during extended testing sessions.
Environmental Monitoring & Safety — Built-in temperature and humidity sensors with real-time display, plus grounding alarm function to alert operators of potential safety hazards before testing begins.
Multi-Standard Compliance — Pre-programmed with GB1986 and GB2002 national standard methods, plus a user-defined custom mode to accommodate diverse testing requirements across different regions and applications.
Precision Oil Cup Design — Three-cup configuration with special glass one-time casting eliminates oil leakage and interference; high-voltage terminal sampling feeds directly to the A/D converter, bypassing analog circuit errors for superior measurement accuracy.
Comprehensive Protection — Integrated over-current, over-voltage, and short-circuit protection with strong anti-interference capability and excellent electromagnetic compatibility for safe operation in electrically noisy environments.
Selectable Boost Rate — Four boost speed options (2.0–3.5 kV/s) allow operators to optimize the test profile for different oil types and condition assessments.
Built-in Thermal Printer — Instant hard-copy output of individual and averaged multi-trial test results for immediate documentation and compliance reporting.
Q1: Is this tester suitable for third-party electrical testing and certification laboratories?
Yes, the XHYY102S is an excellent choice for independent testing laboratories that provide certified oil analysis services. Its compliance with GB/T507-2002 and DL/T846.7-2004 standards ensures results are legally defensible for certification purposes. The three-cup design enables rapid throughput of multiple samples, while the built-in thermal printer generates immediate hard-copy reports with individual trial data and computed averages — ideal for audit trails and client documentation in ISO/IEC 17025 accredited facilities.
Q2: Can this device be used in transformer repair and refurbishment workshops?
Absolutely. Transformer service centers routinely test insulating oil before and after maintenance procedures to verify oil quality. The XHYY102S’s selectable boost rates (2.0–3.5 kV/s) and customizable trial count (1–6 times) provide flexibility for both quick screening and detailed condition assessment. The direct A/D sampling architecture eliminates analog circuit drift, delivering consistent repeatability that repair technicians can rely on when making reconditioning decisions.
Q3: How does it perform in insulating oil recycling and reclamation facilities?
Oil reclamation plants processing large volumes of used transformer oil need rapid, reliable BDV testing to verify that reclaimed oil meets reuse specifications. The XHYY102S’s three-cup configuration enables parallel testing of incoming, in-process, and outgoing oil samples, dramatically improving workflow efficiency. The instrument’s wide-range watchdog circuit and anti-crash protection ensure uninterrupted operation during the extended, continuous testing sessions typical of high-throughput reclamation operations.
Q4: Is it appropriate for transformer manufacturing quality control lines?
Yes. Transformer manufacturers require rigorous oil dielectric testing as part of factory acceptance testing (FAT) before equipment leaves the production line. The XHYY102S supports both GB1986 and GB2002 standard methods, plus a custom-defined mode, allowing manufacturers to program test sequences that match specific customer specifications or international standards. Its microprocessor-controlled, fully automatic operation minimizes operator dependency and ensures consistent, repeatable QC data across production shifts.
Q5: Can this tester be field-deployed by preventive maintenance service contractors?
Independent electrical maintenance contractors serving industrial clients across multiple sites benefit from the XHYY102S’s robust design and self-contained functionality. Despite its 42 kg weight (reflecting a substantial 1.5 kVA booster for reliable 80kV output), the integrated panel layout — combining LCD display, function keys, printer, and controls on a single front panel — enables efficient setup and operation at client substations. The environmental monitoring sensors (temperature and humidity) provide context for each test result, enhancing report credibility for end-customer review.
