Adistribution transformerorservice transformeris atransformerthas muab cov kev hloov pauv zaum kawg hauv cov hluav taws xob hluav taws xob faib hluav taws xob, nqis los ntawm qhov hluav taws xob siv hauv cov kab xa tawm mus rau qib siv los ntawm cov neeg siv khoom.Qhov kev tsim ntawm cov khoom siv hluav taws xob ua tau zoo ua AC fais fab faib ua tau; Lub kaw lus siv cov khoom siv hluav taws xob faib tawm tau pom thaum ntxov li xyoo 1882.
Yog hais tias mounted ntawm autility ncej, lawv hu ua ncej-mount transformers. Yog hais tias cov kab xa tawm nyob rau hauv av los yog hauv av, cov khoom siv hluav taws xob faib hluav taws xob tau teeb tsa rau ntawm cov pob zeb ua vaj tse thiab muab xauv rau hauv cov rooj plaub hlau, yog li hu ua tis tappad-mount transformers.
Distribution transformers ib txwm muaj qhov ntsuas tsawg dua 200kVA, txawm hais tias qee cov qauv hauv tebchaws tuaj yeem tso cai rau chav nyob txog 5000 kVA los piav qhia txog kev faib khoom hloov pauv. Txij li thaum faib cov transformers yog energized rau 24 teev nyob rau ib hnub (txawm tias thaum lawv tsis' tsis nqa ib qho load), reduceiron losseshas lub luag hauj lwm tseem ceeb nyob rau hauv lawv tsim. Raws li lawv feem ntau tsis ua' tsis ua haujlwm ntawm kev thauj khoom tag nrho, lawv tau tsim kom muaj kev ua haujlwm siab tshaj plaws ntawm cov khoom qis. Yuav kom muaj kev ua haujlwm zoo dua, kev tswj hluav taws xob hauv cov hloov pauv no yuav tsum tau khaws cia kom tsawg. Li no lawv tau tsim los kom muaj qhov dej me me reactance.
