XHYY102M Transformer Insulating Oil Breakdown Voltage Tester 80kV Digital Display
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.
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 & FeaturesOne 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:
| Stage | Default | Adjustable Range |
|---|---|---|
| Mixing time | 15s | 0–999s |
| Step-up speed | 0.5–5.0 kV/s, in 0.5 steps (10 gears) | Error 0.2 kV/s |
| Test times | 6 times | 1–9 times |
| Static release time | 900s | 0–9999s |
| Interval rest time | 300s | 0–999s |
| Electrode gap | 2.5mm standard | — |
The instrument program is equipped with GB/T507-1986, GB/T507-2002, DL429.9, IEC156 and self-programming operation, so a single unit adapts to a wide range of choices from different users.
