Transformer Roj Test
- Di-electric Test lossis Break Down Voltage Test
- Viscosity Test
- Acidity Test
Kev ntsuas hluav taws xob tawg
International txuj
- 2.5 hli sib txawv ntawm ob lub electrodes, Applied voltage 25 KV rau 1 min.
- 2.5 mm -25 KV-1 min: Tsis muaj Spark ntawm cov roj, Roj yog ok, Roj siv tau rau txhua theem voltage.
- Energy Pac ua raws li tus qauv no.
- 4.
Kev ntsuas acidity
Qib acidity:
- 0.5 mg KOH/gm (Oil is ok.)
- {{0}}.5 mus rau 1.0 mg KOH/gm (hauv kev soj ntsuam)
- 1.0 mg KOH/mg (Discard Oil)
Viscosity Test
- viscosity ntawm cov roj nce thaum cov tshuaj tiv thaiv oxidation nce.
- Oxidation nce thaum cov roj yaj ntawm cov roj nce ntxiv.
- Los ntawm Dissolved Gas Analysis, cov roj yaj hauv cov roj tuaj yeem txheeb xyuas tau.
- Raws li cov viscosity nce cov roj hloov loj thiab nws txav mus qeeb thiab nws cov peev xwm rwb thaiv tsev maj mam deteriorates.
- viscosity yuav tsum tsawg li tsawg tau.
Rwb thaiv tsev Resistance Test
- Japanese Standard: (Rated Voltage * 2 ntxiv rau 1) KV dc yog siv.
