Raws li peb paub, kev tiv thaiv kev tiv thaiv kev phom sij yuav degrade los yog txawm tuaj mus xaus rau lub neej dhau los vim pheej yig me me, ib qho muaj zog tuaj yeem los yog overvoltage ntev. Thiab thaum muaj kev tiv thaiv ntaus tsis ua hauj lwm, nws yuav tsim ib qho kev mob nkeeg luv luv thiab ua rau muaj teeb meem kev nyab xeeb nyob rau hauv lub zog system. Yog li cov cuab yeej tiv thaiv kev tiv thaiv ntau tshaj yog yuav tsum tau ua hauj lwm ua ke nrog kev tiv thaiv kev tiv thaiv.
Yeej muaj ob hom kev tiv thaiv kev tiv thaiv uas siv ntau tshaj nrog SPD rau kev tiv thaiv kev tiv thaiv: kev sib tsuam thiab kho hluav taws xob. Li ntawd, dab tsi yog lawv cov Pros thiab Cons feem?
