Farqiga u dhexeeya heerarka CSA iyo Ieee ee sedex weji ah

padmount

Pad - Transformers-ka la rakibay waa qaybo muhiim ah oo ku saabsan nidaamyada qaybinta korantada, iyadoo la siinayo isbadal amaan ah oo hufan oo loogu talagalay shabakadaha dhulka hoostiisa ah. Machadka machadka korantada iyo injineerada elektiroonigga ah (Ieee) iyo Ururka Heerka Heerka Kanada (CSA) waxay dejiyeen heerar ay ku xukumaan qaabeynta, tijaabada, iyo waxqabadka. Si kastaba ha noqotee, kala duwanaanshaha muhiimka ah ayaa ka dhex jira heerarka IEEE (Ieee C57.12.34} 2022) iyo heerarka CSA (CSA C227.4-21) marka loo eego awoodda lagu qiimeeyo, iyo dhismaha. Kala duwanaanshahaasi waxay ka tarjumayaan baahiyaha nidaamka korantada ee gobolka, tixgelinta amniga, iyo ku dhaqanka hawlgalka. Wadahadalkani wuxuu sahaminayaa kala soocaya heerarka IEEE iyo Heerarka CSA ee Transform-ka Gawaarida Gawaarida, iyadoo diiradda lagu saarayo qeexitaankooda farsamo iyo saameynta qaabeynta qaab dhismeedka qaab dhismeedka.
