Kasancewar harmonics a cikin tsarin wutar lantarki yayi daidai da tushen gurɓataccen tsarin wutar lantarki, kuma abin gurɓataccen abu shine galibi yanayin lantarki a cikin tsarin wutar lantarki. A matsayin muhimmin ɓangaren muhalli na tsarin wutar lantarki, yanayin lantarki zai nuna haɗari daban-daban a ƙarƙashin tasirin matakan harmonics daban-daban. Duk da haka, wannan mafi ƙarancin cutarwa zai kuma rage ingancin aiki na kayan lantarki, kuma mafi munin sakamako na iya haifar da tsanantawa ga ingantaccen aiki na tsarin wutar lantarki da lalata kayan lantarki. Lalacewar samar da harmonics ta haɗa da waɗannan fannoni:

(1) Kayan lantarki suna dumamawa sosai a ƙarƙashin tasirin harmonics, kuma ƙarin asarar ta yi yawa. Duk da cewa akwai babban gibi tsakanin adadin harmonics da tushen current, kasancewar harmonics zai ƙara ta'azzara tasirin fata na na'urar, kuma juriya mai tasiri zai ƙaru a cikin tsarin jin tasirin fata. Ga wasu kayan aiki na musamman, babban asarar eddy current da asarar hysteresis suma za su faru, kamar kayan lantarki masu ƙarfe. Lokacin da aka canza yanayin raƙuman ruwa zuwa wani mataki, babban girman kololuwar raƙuman ruwa zai ƙara ƙarfin fitar da wani ɓangare. A ƙarƙashin irin wannan yanayi mai yawan amfani, yana da sauƙi a rage tsawon rayuwar kayan lantarki.

(2) Motar na iya haifar da girgizar injiniya. A ƙarƙashin tasirin harmonic currents, filin maganadisu mai juyawa na motar zai samar da ƙarfin juyi wanda zai iya sa injin ya yi rawar jiki. A ƙarƙashin tasirin mitar motar ta halitta, wannan nau'in girgizar na iya haifar da girgizar injiniya mai cutarwa cikin sauƙi, ta haka yana kawo haɗarin ingancin kayan aikin lantarki har ma da barazana ga rayuwar mutane.

(3) Tsangwama ga kayan aikin kwamfuta da sauran na'urorin sarrafawa ta atomatik. A cikin yanayi na yau da kullun, kayan sarrafawa ta atomatik da sauran tsarin sarrafawa ta atomatik masu alaƙa an tsara su ne bisa ga ƙarfin lantarki na yau da kullun da ƙarfin lantarki mai lodi. Lokacin da aka samar da harmonics, tsarin sarrafawa ta atomatik ba ya la'akari da wannan abin da ke tasiri, yana mai sauƙi Tsangwama yana shafar aikin aikinsa na sarrafawa. Lokacin da matakin gurɓataccen harmonics ya yi yawa, yana yiwuwa a canza hanyoyin aiki na tsarin sarrafawa ta atomatik, wanda ke haifar da shi ya haifar da jagora mara kyau.
