Product Description

XHYY102S Three-Cup Insulating Oil BDV Tester is a fully automatic high-voltage diagnostic instrument engineered for precise breakdown voltage testing of insulating oils in transformers, circuit breakers, and oil-immersed electrical apparatus. Power systems, railway networks, large petrochemical facilities, and mining operations depend on extensive electrical equipment where oil-immersed insulation is the primary dielectric protection. Testing the dielectric strength of insulating oil is a non-negotiable routine requirement. Developed in strict compliance with GB/T507-2002, DL429.9-91, and DL/T846.7-2004, this instrument uses a single-chip microcontroller to automate the entire testing workflow — delivering high-precision measurements, dramatically improving operational efficiency, and substantially reducing field personnel workload.

Key Performance Features

Full Automation with MCU Control — Single-chip microcontroller drives the entire test cycle automatically, from voltage ramp to breakdown detection and result averaging. Wide-range watchdog circuit prevents system hangs during extended operation.
Multi-Standard Test Protocols — Pre-loaded with GB1986 and GB2002 national standard methods plus user-defined custom mode, accommodating diverse regulatory requirements and specialized test sequences.
Precision Measurement Architecture — High-voltage terminal sampling feeds directly to the A/D converter, eliminating analog circuit drift for ±(2% + 2 digits) accuracy. Power distortion rate below 1% ensures clean, reliable breakdown detection.
Three-Cup Efficiency — Simultaneous or sequential testing across three oil cups accelerates sample throughput, with selectable trial counts (1–6) and standing times (1–9 min) to match specific test protocols.
Comprehensive Safety Protection — Built-in over-current, over-voltage, and short-circuit protection with grounding alarm function and high-voltage warning indicator ensure operator safety throughout the testing process.
Environmental Sensing & Documentation — Integrated temperature and humidity sensors provide ambient context for each test. Built-in thermal printer generates immediate hard-copy reports of individual and averaged results.

Frequently Asked Questions

Q1: Is this tester suitable for routine substation maintenance programs at power utilities?

Yes, the XHYY102S is purpose-built for utility substation maintenance workflows. Its three-cup configuration enables technicians to test oil samples from multiple transformers or tap-changer compartments in a single session, significantly reducing substation downtime. The instrument’s automated GB1986/GB2002 test protocols align directly with utility preventive maintenance schedules, while the thermal printer provides immediate compliance documentation that integrates seamlessly into station maintenance logs and regulatory audit trails.

Q2: Can commissioning engineers use this for new electrical equipment acceptance testing?

Absolutely. During new transformer and switchgear commissioning, verifying insulating oil dielectric strength is a critical acceptance criterion before energization. The XHYY102S supports user-defined custom test sequences, allowing commissioning engineers to program parameters that match equipment manufacturer specifications or project-specific quality plans. Its ±(2% + 2 digits) voltage accuracy and <1% power distortion rate deliver trustworthy baseline data for equipment handover documentation and warranty validation.

Q3: How does it serve insurance surveyors and electrical asset inspectors?

Insurance and risk assessment professionals evaluating electrical infrastructure require objective, verifiable oil condition data to underwrite policies or assess claims. The XHYY102S’s automated operation minimizes operator subjectivity, producing consistent, repeatable BDV measurements. The printed reports — showing date/time, ambient temperature/humidity, individual trial values, and computed average — provide a complete, tamper-evident record suitable for insurance underwriting files, risk engineering reports, and post-incident forensic analysis.

Q4: Is it suitable for grid operator condition-based maintenance (CBM) programs?

Grid operators transitioning from time-based to condition-based maintenance (CBM) need reliable trending data to make informed asset management decisions. The XHYY102S’s precise, repeatable measurements enable operators to track oil dielectric strength degradation trends across transformer fleets over months and years. The consistent test protocol execution — same boost rate, same trial count, same standing time — ensures that successive measurements are directly comparable, supporting data-driven decisions on oil replacement, reclamation, or equipment retirement.

Q5: Can emergency response teams deploy this tester after natural disasters or grid failures?

Following floods, earthquakes, or severe storms, rapid assessment of transformer oil condition is essential to determine whether equipment can be safely re-energized or requires immediate servicing. The XHYY102S’s robust 42 kg construction with 1.5 kVA booster provides reliable field-grade performance even in compromised post-disaster environments. Its straightforward single-chip microcontroller operation requires minimal training — a critical advantage when specialist crews may not be immediately available and general electrical response teams must perform initial diagnostic screening.
