Mai da shi ne Acidity Test na Transformer?

Takaitar da Acidity Test

Acidity test na mai transformer yana nuna yadda ake bukatar potassium hydroxide (KOH) don in kula acid a cikin mai.

Dalilai na Acidity

Acidity ta faru saboda oxidation, musamman idan mai tana gama da hawa, kuma ana iya haɗa suka tsarki saboda jiha da abubuwa masu iron da copper.

Fadada Acidity

Acidity mai yawa take saukar da resistivity na mai, take sauya dissipation factor, kuma zai iya jan hankali ga insulation na transformer.

Kompoonenti na Acidity Test Kit

Zan iya tabbatar da acidity na mai insulating na transformer, tun daga kit mai acidity mai kyau. Ana ciki da polithene bottle na rectified spirit (ethyl alcohol), polithene bottle na sodium carbonate solution, da kuma bottle na universal indicator (liquid). Kuma ana ciki da test tubes mai lafiya da syringes mai volumetrically scaled.

 Principle of Acidity Test of Insulating Oil

 Idan alkali ya zama a cikin mai, zai yi canza acidity na mai mafi yawan acid da ke cikin. Idan alkali da aka bayar yana da damar acid da ke cikin, pH na mai zai 7 (neutral). Alkali masu yawa zai yi oil alkaline (pH 8-14), kuma alkali masu yaro zai yi oil acidic (pH 0-6). Universal indicator yana nuna rangoda daban-daban don pH daban-daban, wanda yake iya bayyana muni da acidity na mai.

Acidity of Insulating Oil Measure

Acidity na mai insulating oil yana kunna da amount of KOH (a milligrams) da ke bukatar don in kula acid a cikin amount of oil (a grams). Misalai, idan acidity na mai yana 0.3 mg KOH/g, yana nufin cewa 0.3 milligrams of KOH da ke bukatar don in kula 1 gram of the oil.

Testing Procedure

Procedure ta faru saboda addin specific amounts of rectified spirit, sodium carbonate, and a universal indicator to the oil and observing the color change to determine acidity.
