Frequently Asked Questions
Q1: What international testing standards does the XHYY102 comply with?
The XHYY102 supports multiple internationally recognized testing standards including GB507-1986, GB507-2002 (Chinese national standards), DL/429 (electric power industry standard), and IEC156 (International Electrotechnical Commission). Custom testing protocols can also be configured to meet specific laboratory or regional requirements, making the instrument suitable for global deployment in transformer manufacturing, utility maintenance, and third-party testing facilities.
Q2: What oil cup configurations are available and how do they affect throughput?
The XHYY102 is available in single-cup, three-cup, and multi-cup configurations. The single-cup model is ideal for low-volume laboratory testing. The three-cup version enables parallel testing of multiple oil samples simultaneously, significantly improving throughput for transformer maintenance depots and service companies. All oil cups are manufactured from special glass using one-step casting technology, ensuring leak-proof operation and consistent electrode gap alignment at the standard 2.5mm spacing.
Q3: How does the boost speed adjustment work and why is it important?
The XHYY102 offers ten adjustable boost speed levels from 0.5kV/s to 5.0kV/s (incremented every 0.5kV/s) with a speed accuracy of 0.2kV/s. Precise boost rate control is critical for dielectric strength testing because different standards specify different voltage ramp rates. For example, IEC156 requires a uniform 2kV/s rate, while some national standards allow different speeds. The ability to select the exact boost rate ensures full compliance with the target test standard and produces reproducible, legally defensible results.
Q4: What safety and protection mechanisms are integrated into the instrument?
The XHYY102 incorporates multiple layers of protection: over-current protection prevents damage from unexpected current surges, over-voltage protection safeguards both the instrument and operator at the 80kV output level, and short-circuit protection handles accidental fault conditions. The instrument features reliable ground connection, indicator lights showing active operation steps, and a lid interlock system that prevents high-voltage output when the oil cup compartment is open. Strong electromagnetic compatibility ensures reliable operation even in electrically noisy substation environments.
Q5: What are the MOQ, warranty coverage, and customization options for volume procurement?
The minimum order quantity is 1 unit, with payment via T/T or L/C. Standard delivery is 5-10 working days in a protective aluminum alloy carrying case. Each instrument includes a 12-month comprehensive warranty with lifetime technical support. Custom voltage ranges (beyond 80kV), specialized oil cup configurations, and OEM branding are available upon request. Annual supply capacity reaches 500 units.
