A maara nke ọma na ngwaahịa eletrọnịkị na-ezutekarị transients voltaji a na-atụghị anya ya na nke a na-eji eme ihe, nke na-eduga n'imebi ngwaahịa eletrọnịkị.Ihe mebiri emebi bụ ngwaọrụ semiconductor dị na ngwaahịa eletrọnịkị (gụnyere diodes, transistor, SCR na sekit agbakwunyere) na-ere ọkụ ma ọ bụ gbarie.

Kewapụ usoro tumadi na-eji iche iche transformer na shielding Layer.N'ihi na nkịtị-mode nnyonye anya bụ ụdị dịtụ terrestrial nnyonye anya, ọ na-ebute site ná tumadi site njikọ capacitance n'etiti transformer windings.If a shielding oyi akwa na-etinyere n'etiti isi na nke abụọ, na A na-agbanye oyi akwa mkpuchi nke ọma, enwere ike ịgbanye voltaji na-egbochi ya site na oyi akwa mkpuchi, si otú a na-ebelata voltaji na-etinye aka na mmepụta.

Theoretically, na transformer na shielding oyi akwa nwere ike ime ka attenuation nke banyere 60dB.Ma mwepu mmetụta dị mma ma ọ bụ ihe ọjọọ, na-emekarị na-adabere na shielding oyi akwa technology.Ọ kasị mma ịhọrọ 0.2mm oké ọla kọpa efere, mbụ n'akụkụ, osote n'akụkụ. nke ọ bụla na-agbakwụnye ihe mkpuchi mkpuchi. Ọtụtụ mgbe, a na-ejikọta ihe mkpuchi nke mbụ na mkpuchi nke abụọ site na capacitor, nke a na-ejikọta ya na ala nke abụọ. , na mkpuchi mkpuchi nke ọnụ ụzọ nke abụọ nwere ike jikọta ya na ala nke nsọtụ.

Absorbing usoro tumadi na-eji ife absorbing ngwaọrụ banye na nnyonye anya voltaji nke anya peak.Absorbing ngwaọrụ niile nwere a nkịtị e ji mara, ya bụ, ha na-ewetara elu impedance n'okpuru ọnụ voltaji, na ozugbo ọnụ ụzọ voltaji bụ gafere, impedance tụlee sharply, ya mere. ha nwere mmetụta mgbochi ụfọdụ na oke voltaji.
