Whakarāpopototanga
hw32-12F raupapa waho AC ngaohiko teitei mohio korehau ara iahiko breaker(i muri nei ka kiia ko te ara iahiko breaker) he pai mo te 12kV me raro, AC 50H2 whatunga taone me te punaha tohatoha mana tuawhenua. He mahi rapu he, he mana tiaki me te mahi korero. Ka whakauruhia ki roto i te 12kV o runga o te raina o te waahi wehewehenga kawenga, ka taea te mohio ki te tapahi aunoa, te waahi kotahi-waahanga me te wehe aunoa i te he o te waahi poto. He pai mo te hurihanga raina tohatoha hiko me te hanga aunoatanga whatunga tohatoha. hua
Ka taea te whakahaere a-ringa i te ara iahiko, te mahi hiko, te mahi mamao me te mahi mamao. E toru nga wahanga o te wehenga ara iahiko: te tinana, te tikanga whakahaere me te mana whakahaere. Ko te pana wehe ka whakauruhia e te kaiwhakamahi. Ka taea te whirihora i te ara iahiko me te CT whakamarumaru o naianei huringa) ZCT(Zero-sequence current transformer) me PT(Voltage Transformer) hei kaitirotiro o te kaiwhakahaere.
