BTF Yekuongorora Lab Electromagnetic Compatibility (EMC) sumo

tsananguro pfupi:

Electromagnetic kuenderana (EMC) inoreva kugona kwechishandiso kana sisitimu kushanda zvinoenderana munzvimbo yayo yemagetsi pasina kukonzera kukanganiswa kwemagetsi kune chero mudziyo uri munharaunda yayo. Naizvozvo, EMC inosanganisira zviviri zvinodiwa: Kune rimwe divi, zvinoreva kuti kukanganiswa kwemagetsi kunokonzerwa nemidziyo kunharaunda mune yakajairika maitiro ekushanda hakugone kupfuura imwe muganhu; Nekune rimwe divi, zvinoreva kuti mudziyo une imwe dhigirii yekudzivirira kune electromagnetic kukanganiswa munharaunda, kureva, electromagnetic sensitivity.

Iyo EMC yakajairwa sisitimu masisitimu emasangano mazhinji epasi rose anotora yakajairwa classification system yeInternational Electrotechnical Commission (IEC), iyo yakakamurwa muzvikamu zvitatu: basic standards, general standards, uye zvigadzirwa zviyero. Pakati pavo, zviyero zvechigadzirwa zvakakamurwazve kuita akateedzana zvigadzirwa zviyero uye yakakosha zvigadzirwa zviyero. Mhando yega yega yechiyero inosanganisira zvese kupindira uye anti-kupindira zviyero. EMC zviyero zvinogamuchirwa zvinoenderana nehurongwa hwe "special product standards → zvigadzirwa zviyero → general standards".
