Isigaba sesi-3 – Iqondwa kanjani incazelo “yefrikhwensi elinganiselwe”

isilinganiso esilinganiselwe: imvamisa eyabelwe into esetshenziswa umkhiqizi.

Ngokuvamile, imvamisa elinganiselwe imvamisa yokusetshenziswa okujwayelekile yezwe lemakethe eliqondiwe ngesikhathi umkhiqizo uklanywa. Njengoba emhlabeni wonke, kukhona amaza okusebenza amabili kuphela, i-50Hz kanye ne-60Hz, inani lingaba ngu-50Hz noma u-60Hz kuphela, noma womabili u-50 kanye no-60Hz.

Imvamisa elinganiselwe, amandla amanje alinganiselwe noma alinganiselwe, i-voltage elinganiselwe, njll. amapharamitha ayisisekelo abonisa into esetshenziswayo, asuselwe ezidingweni zemakethe eqondiwe kanye nezimo zokusetshenziswa.
Uma sihlola ngokwezinga, sibeka izimo zethu zokuhlola ngokwale mingcele. Ngakho-ke, le mingcele kufanele iqinisekiswe ngaphambi kokuhlolwa, ngaphandle kwalokho izoholela ekuphindaphindweni komsebenzi, futhi ikhiqize imiphumela yokuhlolwa engalungile.
