Raws li nws txoj haujlwm ua haujlwm, SPD tuaj yeem muab faib ua hom hloov hluav taws xob, hom kev txwv hluav taws xob thiab hom sib xyaw ua ke.
⑴ Voltage hloov hom SPD. Nws nthuav tawm qhov siab impedance thaum tsis muaj tam sim no overvoltage. Thaum nws teb rau ib qho hluav taws xob tam sim ntawd overvoltage, nws impedance hloov mus rau qhov tsis muaj impedance, cia xob laim tam sim no dhau mus. Nws tseem hu ua "luv-circuit hloov hom SPD".
⑵ Siab-limiting SPD. Thaum tsis muaj tam sim no overvoltage, nws muaj impedance siab, tab sis raws li qhov surge tam sim no thiab voltage nce, nws impedance tseem yuav txo qis, thiab nws cov yam ntxwv tam sim no thiab voltage tsis muaj zog, qee zaum hu ua "clamp-type SPD".
⑶ Ua ke SPD. Nws yog tsim los ntawm ib tug voltage switching yam tivthaiv thiab ib tug voltage limiting hom tivthaiv. Nws tuaj yeem tso saib cov yam ntxwv ntawm kev hloov hluav taws xob, hom kev txwv hluav taws xob lossis ob qho tib si, nyob ntawm tus yam ntxwv ntawm qhov siv hluav taws xob.
