XHYY102 Transformer Insulation Oil Dielectric Strength Tester — a fully digital instrument that checks the dielectric strength (breakdown voltage) of transformer insulating oil up to 80kV, with automatic microcomputer control.
Overview
The XHYY102 is a high-accuracy, fully digital industrial instrument developed in accordance with the national standard GB507-1986 and the industry standard DL/T846.7-2004. To suit different users, the series is available in single-cup, three-cup and multi-cup models. The instrument is easy to operate and attractive in appearance; thanks to fully automatic digital microcomputer control, it offers high measurement accuracy, strong anti-interference and safe, reliable operation.
Main Functions & Features
Controlled by a large-capacity microcontroller — stable and reliable operation.
Equipped with a wide-range watchdog circuit to prevent crashes.
Oil cup cast in one step from special glass, eliminating interference such as oil leakage.
Unique high-voltage side sampling design — the test value enters the A/D converter directly, avoiding errors caused in the analog circuit and making results more accurate.
Built-in over-current, over-voltage and short-circuit protection, with strong anti-interference and good electromagnetic compatibility.
Portable structure, easy to move and to use indoors and outdoors.

Who It Is For
The XHYY102 is aimed at the teams that qualify and monitor transformer insulating oil:
Power generation and supply companies’ oil and chemical supervision laboratories running routine and acceptance dielectric-strength tests on transformer insulating oil.
Transformer manufacturers checking the oil used for oil-immersed products on the factory test bench.
Transformer oil producers and oil regeneration / reclamation service companies verifying the breakdown voltage of new and reclaimed oil.
Research institutes and third-party testing laboratories performing breakdown tests to GB507, IEC156 and DL/429.
Frequently Asked Questions
What does the XHYY102 test?
It measures the dielectric strength (breakdown voltage) of transformer insulating oil, in accordance with standards such as GB507-1986, GB507-2002, DL/429 and IEC156.
What output voltage and accuracy does it provide?
It provides an output voltage of 0–80kV with a measuring accuracy of ±3% and a voltage distortion rate below 3%.
Which test methods are built in?
The program includes two national standard methods (GB507-1986 and GB507-2002), the industry standard DL/429, the international standard IEC156 and customized operation.
Is the testing automatic?
Yes. The instrument uses fully automatic digital microcomputer control, with adjustable voltage raising speed (0.5–5 kV/s), standing time (15min), boosting interval (5min) and boosting frequency (1–9 times).
Why are the readings accurate and safe?
The unique high-voltage side sampling design feeds the test value directly into the A/D converter to avoid analog-circuit errors, while built-in over-current, over-voltage and short-circuit protection and a watchdog circuit keep operation safe and reliable.
Convenient and Portable
With its portable structure, the XHYY102 is easy to move and convenient for both indoor and outdoor use. Please contact us for the cup configuration (single-cup, three-cup or multi-cup) that best suits your testing volume.
