1) Modulu chaja na-eji usoro mwepụ okpomọkụ nke na-ejikọta oyi onwe ya na oyi ikuku, ma na-agba oyi onwe ya n'oge ibu dị mfe, nke kwekọrọ na ọrụ nke sistemụ ike ahụ n'ezie.

2) Ọ bụ modulu nhazi kachasị mkpa nke ọkọnọ ike, a na-ejikwa ya nke ọma na ọkọnọ ike nke ọdụ ndị na-anọchi site na 35kV ruo 330kV.
2. Ọrụ nchekwa nke modulu chaja ikuku

1) Ntinye nchekwa voltaji karịrị/n'okpuru

Modulu ahụ nwere ọrụ nchekwa ntinye n'elu/n'okpuru voltaji. Mgbe voltaji ntinye erughị 313±10Vac ma ọ bụ karịa 485±10Vac, a na-echekwa modulu ahụ, enweghị mmepụta DC, a na-agbakwa ihe ngosi nchekwa (odo). Mgbe voltaji ahụ gbakechara ruo n'etiti 335±10Vac～460±15Vac, modulu ahụ na-amaliteghachi ọrụ na akpaghị aka.

2) Nchedo oke voltaji/mkpọsa voltaji

Modulu ahụ nwere ọrụ nke nchekwa oke voltaji mmepụta na mkpu voltaji na-adịghị ike. Mgbe voltaji mmepụta karịrị 293±6Vdc, a na-echekwa modulu ahụ, enweghị mmepụta DC, ihe ngosi nchekwa (odo) na-agba. Modulu ahụ enweghị ike ịgbake na akpaghị aka, a ga-agbanyụkwa modulu ahụ wee gbanye ya ọzọ. Mgbe voltaji mmepụta erughị 198±1Vdc, mkpu modulu ahụ, enwere mmepụta DC, ihe ngosi nchekwa (odo) na-agbakwa. Mgbe voltaji eweghachiri voltaji ahụ, mkpu voltaji mmepụta modulu na-apụ n'anya.

3. Nkwụsịtụ obere sekit

Modulu ahụ nwere ọrụ mwepụ mkpụmkpụ. Mgbe mmepụta modulu dị mkpụmkpụ, ọkụ eletrik anaghị agafe 40% nke ọkụ eletrik enyere ọkwa. Mgbe ewepụsịrị ihe dị mkpụmkpụ, modulu ahụ na-eweghachi mmepụta nkịtị na akpaghị aka.

4. Nchedo mfu nke usoro

Modulu ahụ nwere ọrụ nchekwa mfu nke usoro. Mgbe usoro ntinye ahụ na-efu, ike nke modulu ahụ pere mpe, a pụkwara ibufe mmepụta ahụ ọkara. Mgbe voltaji mmepụta ahụ bụ 260V, ọ na-ewepụta ọkụ 5A.

5. Nchedo okpomọkụ karịrị oke

Mgbe ikuku dị n'ime modulu ahụ kpọchiri akpọchi ma ọ bụ okpomọkụ dị n'ime modulu ahụ dị oke elu ma okpomọkụ dị n'ime modulu ahụ gafere uru edobere, a ga-echebe modulu ahụ pụọ na oke okpomọkụ, ihe ngosi nchekwa (odo) dị na panel modulu ahụ ga-adị, modulu ahụ agaghịkwa enwe mmepụta voltaji. Mgbe a kpochapụrụ ọnọdụ ahụ na-adịghị mma ma okpomọkụ dị n'ime modulu ahụ laghachi na nkịtị, modulu ahụ ga-alaghachi na ọrụ nkịtị na akpaghị aka.
6. Nchedo oke ọkụ n'akụkụ bụ isi

N'ọnọdụ na-adịghị mma, oke ọkụ na-eme n'akụkụ rectifier nke modulu ahụ, a na-echekwa modulu ahụ. Modulu ahụ enweghị ike ịgbake na akpaghị aka, a ga-agbanyụkwa modulu ahụ wee gbanye ya ọzọ.
