XHYY102M Insulating Oil Breakdown Voltage Tester — a high-accuracy, full digital instrument that measures the breakdown voltage of transformer insulating oil up to 80kV, with automatic microcomputer control.
Overview
The XHYY102M is a high-accuracy, full digital industrial instrument developed according to the relevant standards and regulations of insulating oil testing. The machine is easy to operate and beautiful in shape; because it uses automatic digital microcomputer control, it delivers high measurement accuracy, strong anti-interference and safe, reliable operation.
Main Functions & Features
Controlled by a large-capacity single-chip microcomputer — stable and reliable.
Temperature, humidity and clock display functions, with a customizable infrared oil temperature measurement option.
Wide-range watchdog circuit to prevent crashes.
Oil cup made of special glass and high-polymer materials, finely processed to prevent oil leakage and corrosion.
Unique high-voltage sampling design — the test value enters the A/D converter directly, avoiding errors from 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.
Can switch between Chinese and English at will to meet the needs of any customer.
RS232 data transfer for communication with a computer.
A Fully Automatic Test Cycle
One test is run automatically from mixing, through step-up, to breakdown — and the operator can tune each stage. The default values and adjustable ranges are:

Who It Is For
The XHYY102M suits teams that run repeated oil breakdown tests as part of oil handling and maintenance:
Insulating oil reclamation and oil treatment service providers verifying the breakdown voltage of oil before and after filtration.
Power plant electrical testing and maintenance teams carrying out on-site oil BDV checks during maintenance outages.
Transformer oil distributors and suppliers checking incoming and outgoing oil batches.
Testing, calibration and training institutions running standardised breakdown tests with repeatable automatic cycles.
Frequently Asked Questions
