1.1 Nkọwa oru ngo

1000/1150 kVA substation transformer e zigara America na 2025. The gosiri ike nke transformer bụ 1000/1150 kVA na KNAN/KNAF jụrụ. The isi voltaji bụ 13.8 kV na ± 2 * 2.5% tapping nso (NLTC), nke abụọ voltaji bụ 0.48GrdY / 0.277 kV, ha guzobere vector otu Dyn1.

Emebere ihe ngbanwe nke 2000/2300 kVA iji wepụta nkesa ike a pụrụ ịdabere na ya maka ụlọ Junction - 1. Transformer jupụtara na mmiri mmiri FR3® dielectric, mmanụ na-adịgide adịgide ma dị elu{{4}mmanụ na-eme ka ọ dị elu nke na-eme ka nkwụsi ike nke okpomọkụ dịkwuo elu, na-agbatị ndụ akụrụngwa, ma na-enye nchekwa gburugburu ebe obibi dị elu ma e jiri ya tụnyere mmanụ ịnweta mmanụ.

Otu akụkụ nchekwa dị mkpa nke sistemu a bụ 5-amp neutral grounding resistor (NGR), nke na-amachi mmejọ nke ugbu a ma na-echebe onye ngbanwe site na mmebi n'oge mmejọ ala. A na-enyocha NGR site na ngbanwe dị ugbu a nke 5: 5 (CT) nwere ogo C10 ziri ezi, na-ahụta nchọta mmejọ na nchedo sistemu.

Emebere ya maka ịdịte aka yana nnabata n'ụkpụrụ ụlọ ọrụ, transformer a na-ahụ maka nnyefe ike kwụsiri ike ma na-ebute nchekwa, nkwado na arụmọrụ arụmọrụ maka Ụlọ Junction - 1.
