Three-Cup Insulation Oil Dielectric Strength Tester 80kV Automatic for GB IEC Transformer Laboratory Testing|XHYY102S

The XHYY102S Three-Cup Insulation Oil Dielectric Strength Tester is a high-capacity, fully automatic industrial instrument purpose-built for electrical power systems, railway networks, and large petrochemical facilities that manage extensive fleets of oil-filled electrical equipment. Independently developed in accordance with GB/T507-2002, DL429.9-91, and DL/T846.7-2004 standards, the XHYY102S employs a single-chip microcontroller core to achieve full test automation with exceptional measurement precision, dramatically improving laboratory throughput while reducing operator workload.

Engineered as the high-throughput variant in the XHYY102 series, the XHYY102S features three independent oil cup positions for simultaneous testing of three samples in a single run. Each oil cup is manufactured from special glass using one-time casting technology to eliminate leakage and interference phenomena. The instrument incorporates a grounding alarm system for enhanced operator safety, integrated temperature/humidity/clock display, and a wide-range watchdog circuit for crash-free continuous operation. A dedicated boost rate switch provides instant selection between four standardized speed settings (2.0/2.5/3.0/3.5 kV/s).

• Three-Cup Simultaneous Testing: Three independent oil cup positions enable parallel dielectric strength measurement of three samples in a single automated run, tripling laboratory throughput
• Single-Chip Microcomputer Control: Large-capacity microcontroller with wide-range watchdog circuit ensures stable, reliable, crash-free operation for continuous heavy-duty use
• Grounding Alarm System: Dedicated safety feature monitors ground connection integrity and alerts operators to potential hazards before high-voltage testing begins
• Dedicated Boost Rate Switch: Physical selector for instant switching between 2.0, 2.5, 3.0, and 3.5 kV/s rates with 0.2kV/s accuracy, eliminating menu navigation during protocol changes
• Environmental Monitoring: Integrated temperature and humidity sensors with real-time digital display for comprehensive test condition documentation
• High-Voltage Direct Sampling: Unique high-voltage terminal design feeds test values directly to the A/D converter, bypassing analog circuit errors for superior accuracy
• Multi-Standard Compliance: Pre-loaded with GB1986, GB2002, and user-defined custom protocols to accommodate diverse testing requirements
• Comprehensive Protection Suite: Over-current, over-voltage, and short-circuit protection with strong electromagnetic compatibility for reliable substation and factory floor deployment
• Built-in Thermal Printer: Automatic printing of individual and averaged multi-test results for immediate documentation
• Rugged Construction: Heavy-duty 42kg chassis (670x420x410mm) with special glass one-piece cast oil cups for leak-proof, long-service-life operation
