Key Performance Features
Wide-Range Adjustable Output — 0–80 kV continuously adjustable output voltage accommodates testing of insulating oils across all common voltage classes, from distribution transformers through transmission-level equipment, without requiring multiple dedicated test sets.
Flexible Cup Configuration — Available in single-cup, three-cup, and multi-cup variants to precisely match throughput needs and budget parameters, from occasional field testing to routine laboratory operations.
Fully Automatic Microcomputer Control — Large-capacity microcontroller with wide-range watchdog circuit automates the entire test sequence — from voltage ramp through breakdown detection to result averaging — eliminating operator variability and ensuring consistent, repeatable measurements.
Adjustable Test Parameters — Individually configurable boost speed (0.5–5.0 kV/s), standing time (15 min, adjustable), boost interval (5 min, adjustable), and test frequency (1–9 times) enable flexible protocol customization for different oil types and standards.
Multi-Standard Protocol Support — Pre-loaded with GB507-1986, GB507-2002, DL429, IEC156, and user-defined custom protocols for seamless deployment across domestic and international regulatory environments.
Precision Oil Cup Design — Special glass one-piece cast oil cup eliminates leakage and interference phenomena, while high-voltage side sampling feeds directly to the A/D converter for accurate, drift-free measurements.
Comprehensive Protection & Monitoring — Integrated over-current, over-voltage, and short-circuit protection with temperature and humidity sensing, ground monitoring, and operation status indicators for safe, informed testing.
On-Site Documentation — Built-in thermal printer generates immediate hard-copy test reports with all trial data for real-time compliance documentation and maintenance record-keeping.

Frequently Asked Questions
Q1: Is this test set suitable for electrical wholesale distributors and importers stocking for diverse customer bases?
Yes, the XHYY102 is an ideal stock item for electrical equipment distributors and importers who supply to varied end-user segments. Its 0–80 kV adjustable output covers the full range of common transformer oil testing requirements, meaning a single product SKU can serve customers from distribution transformer workshops to transmission equipment maintainers. The three cup-configuration options (single, three, multi) allow distributors to offer tiered pricing and throughput levels without managing inventory of entirely different instrument lines. Its compliance with both GB and IEC standards makes it suitable for both domestic Chinese and export-oriented distribution channels.
Q2: Can generator and electric motor repair/rewinding shops use this for insulating oil testing?
Absolutely. Generator and large motor repair shops that handle oil-cooled or oil-insulated rotating machines need to verify oil condition during overhaul and before returning equipment to service. The XHYY102’s adjustable output voltage and configurable boost speed allow technicians to match test parameters to the specific oil types and equipment classes encountered across different repair jobs. Its straightforward function-key operation means general repair technicians can perform reliable oil testing without being high-voltage testing specialists, while the thermal printer generates documentation that accompanies equipment back to the customer as part of the repair quality package.
Q3: Is it suitable for solar farm and battery energy storage facility O&M teams?
Solar photovoltaic farms and battery energy storage systems (BESS) rely on step-up transformers and auxiliary power transformers to interface with the grid. These facilities, often in remote locations with harsh environmental conditions, need practical on-site oil testing capability. The XHYY102’s wide operating temperature range (0℃ to +45℃) accommodates the hot, arid environments typical of solar installations, while its portable design and self-contained operation eliminate reliance on distant laboratories. O&M teams can perform scheduled oil condition checks during routine site visits without specialized high-voltage training beyond standard electrical safety qualifications.
Q4: Can government electrical standards and metrology bureaus use this for field verification?
Standards and metrology agencies responsible for verifying electrical testing equipment in the field need reference-grade instruments that are both portable and sufficiently accurate for compliance auditing. The XHYY102’s ±3% measurement accuracy and compliance with GB507 and IEC156 standards provide a defensible basis for field verification of other oil testers and for spot-checking transformer oil condition during regulatory inspections. Its fully automatic operation eliminates operator-dependent measurement variation — critical for metrology applications where measurement uncertainty must be controlled and documented.
Q5: Is it appropriate for electrical safety consultancies and training providers?
Electrical safety consultancies that conduct site audits, risk assessments, and condition surveys across multiple client facilities benefit from the XHYY102’s combination of portability, standards compliance, and ease of use. Consultants can perform on-the-spot oil testing during facility walk-downs and include verified BDV data in assessment reports — moving beyond visual inspection to quantitative condition analysis. Training providers delivering courses on transformer maintenance and high-voltage safety can use the instrument’s clear LCD display and logical function-key workflow as an instructional tool that demonstrates real-world testing procedures without the complexity of advanced touch-screen interfaces.
