Pali njira zambiri zochepetsera kuchuluka kwa shuga.Nthawi zambiri, njira yochepetsera kukana imagwiritsidwa ntchito kupondereza kuchuluka kwamphamvu kwamagetsi ang'onoang'ono ndi apakatikati.

Ma thermistors a NTC, omwe amadziwikanso kuti ma thermistor olakwika a kutentha kwapakati, amadziwika ndi kutsika kwapang'onopang'ono kwa mtengo wotsutsa pomwe kutentha kumawonjezeka.NTC nthawi zambiri imagawidwa mu thermistor yoyezera kutentha ndi thermistor yamtundu wa mphamvu pakugwiritsa ntchito.NTC thermistor yomwe imagwiritsidwa ntchito kupondereza kuthamanga imatanthawuza mtundu wa mphamvu ya thermistor.

Pa kutentha kwa chipinda, NTC thermistor ili ndi mtengo wotsutsa kwambiri, womwe ndi wodziwika kuti zero mphamvu zokana mphamvu.Monga 10 Ω concatenated NTC, boot surge panopa kwa: I = 220 x 1.414 / (1 + 1) = 28 (A), zambiri kuposa 311 A osati pogwiritsira ntchito NTC thermistor yafupika nthawi 10, imagwiranso ntchito yoletsa kuthamanga kwapano.

Kuthamanga pambuyo, chifukwa cha kutentha kwa kutentha kwa NTC, kutentha kumakwera mofulumira, kukana kwake kukanakhala mu nthawi ya millisecond kumatsika mofulumira kufika pamtunda waung'ono, kawirikawiri ndi gawo limodzi la kukula kwa Ulaya ku Ulaya angapo, poyerekeza ndi kukana kokhazikika kwachikhalidwe. panopa kuchepetsa resistor, kutanthauza kuti kukana pa mowa mphamvu kwa kugwa kukaniza amachepetsa zigoli kwa kazana, kotero mapangidwe ndi oyenera kwambiri pempho apamwamba kutembenuka dzuwa ndi zinthu zopulumutsa mphamvu, monga kusintha magetsi.

Pambuyo pa kulephera kwa mphamvu, NTC thermistor ndi kuzizira kwake, mtengo wotsutsa udzabwezeretsa pang'onopang'ono ku mtengo wotsutsa mphamvu wa zero, nthawi yobwezeretsa imafunika masekondi makumi angapo mpaka mphindi zingapo.Nthawi ina mukayamba, bwerezani ndondomekoyi.
