Ikaramu ikaramu
Imiryango myinshi yo mu Bwongereza irahabwa na sisitemu ya PME (Kurinda Isi nyinshi), aho isi yishakiye yiruka ku itangwa risanzwe rihujwe nuyobora kutabogamye bushyizwe ku ngingo nyinshi. Izi sisitemu zifite ubushobozi bwo gutanga amakosa adasanzwe yiswe kunanirwa kutabogamye, aho guhagarika kwa hejuru bitewe no gutesha agaciro cyangwa kwangirika bishobora kongera ibyago byamashanyarazi.
Ikaramu idahwitse: Kuri TN-CS Sisitemu ntagukanze kumukoresha (nkuko bigaragara hejuru), iyo ikaramu yumurongo uri hejuru yaciwe kubera umurongo wikaramu , hamwe no gukwirakwiza agasanduku RCD ntabwo ikora neza muriki gihe, voltage yubutaka burinda pe ihwanye na voltage yumuriro wumuriro l.
Niba bidafite agaciro hamwe nuburinzi, igikonoshwa cya EV mu kwishyurwa kizashishikarizwa na voltage angana numuriro wumuriro l
voltage. Niba nta yindi ngero zihari usibye amashanyarazi ya EV, ikigezweho kizarenza 30ma kandi umuntu ntazashobora guhagarika, akaba ari akaga; Niba hari nibindi bikoresho, umurongo ugenda birashobora kurenga 100ma, bica cyane.
