1.1 Nkọwa oru ngo

N'April 2025, otu onye n'ime ndị ahịa anyị ogologo oge{1} na Guyana nyere iwu maka transformer abụọ: 1000kVA 13.8kV–460Y/266V atọ{{6}phase pad- nke etinyere na transformer na 400kVA 460–220/127VPIakọrọ{0}ụdị transformer.

1000 kvampe mpe akwa transformerarụnyere na IEEE Std C57.12.34-ụkpụrụ 2022 yana njiri atụmatụ nri loop nwere ihe nrụnye ihu n'ihu-. Ọ na-anabata ONAN (Oil Natural Air Natural) jụrụ oyi ma were mmanụ ịnweta kpuchie ya. Isi voltaji bụ 13.8kV, na voltaji nke abụọ bụ 460Y/266V, yana otu Dyn11 vector na 5.75% impedance.

Ihe ngbanwe ahụ nwere fuses Bayonet atọ yana ELSP atọ ugbu a- na-amachi fiusi ndabere. Bayonet Fuse na-enye nchebe maka obere mmejọ dị ugbu a. ELSP Fuse na-ebipụ ngwa ngwa ma na-amachi ike arc mgbe sekit dị mkpụmkpụ dị ugbu a na-eme. Mgbe ejikọtara ya, ọ na-ekpuchi oke nchedo mmejọ site na ala ruo ugbu a dị elu. Ọ dabara nke ọma maka mkpa nke nchekwa, kwụsiri ike, dị mfe idowe yana ọnụ ahịa -sistemụ nkesa ike dị irè.

1000 kVA three{1}phase pad mount transformer dabara adaba maka nnukwu ụlọ ahịa & ebe azụmahịa{2}}kV ejikọrọ na netwọk nkesa obodo, yana 460V ka a na-eji maka ikuku ikuku, ọkụ, igwe mbuli elu na ibu ndị ọzọ. N'ihi na ngwa ngwa dị iche iche nke ngwa azụmahịa chọrọ ọkụ ọkụ atọ{5} nke kwụsiri ike, nrụpụta ngbanwe nke 460Y/266V ezuola.
