Misalai na Digitalicition a cikin IEE-Business 61850 a fagen tashar rarrabe masu sarki

Amfani da Rogowski coils don ci masu karamin kashi, voltage dividers don ci masu karamin voltaji, da digital bus don gano abubuwa na switchgear da measured values yana iya inganta tashar waniyar aiki daga cikin hanyoyi. Wannan tashar yana taimaka wajen inganta flexibility da efficiency a cikin tashar da amfani ga electrical system.

Don cikin protection functions na bako daya na Intelligent Electronic Device (IED), line - to - ground currents suna karamin kashi daidai a duk feeder. A incoming feeders, resistive dividers suna kunshi da cables, ta tabbata shi ne necessary voltage measurements zuwa IEDs a kan feeders.

Outgoing feeder protection schemes ba da kyau suke bukatar bayanai na busbar voltage. Misali, a section A, wani outgoing feeder an yi fitowa da resistive voltage dividers wanda suka kunshi da section A busbar system. Kuma, a bus coupler a wannan setup, akwai resistive voltage dividers wanda suka kunshi da section B busbar system.

IEDs a kan feeders ya kamata zai iya amfani da measured voltage don cikin protection schemes, kuma za su tattara voltage-sampled measured data zuwa digital communication network. Wannan yana taimaka masu IEDs, musamman idan suka nan a section A ko B, zuwa canza wannan digital voltage measurement don cikin protection requirements.

Duk da haka, switchgear events suna gani a kan duk feeders, wanda shi ne muhimmanci don implement switchgear control, blocking, da interlocking logic. Wannan gani na bayanai yana taimaka wajen coordinated da reliable operation of the switchgear, tare da yake inganta overall safety da stability na electrical system.
