Hustu Hirikia: GIL-en Txertatutako Korronte-Transformadoreak
Ⅰ. Nukleoa Innovatibidea: CTen eta transmitazio infraestrukturaren integrazio profunda
- Lanbide nulua: Instalazioak kanpo CT tradizionalak bertan behera eraman, zehaztasun-sensorei unitateak zuzenean tenperatura-altu mailako gas-insulated pipeline-en barnean txertatuz, gainetik 90% baino gehiago gorriztu.
- Ingurumen osoko isolamendua: Neurketa-osagaiak hermetiko itxita dagoen gas-kamarroetan kokatuta, ur, ega, sal-erosio eta vandalismoaren arriskuen kendu, instalazioak kanpo dauden baino handiagoa fiabilitatea.
- Bihurri elektromagnetikoa: GIL metalikoen inguruneak Faraday kaxa naturala osatzen du, kanpo EMI blokeatzen du eta CT magnetikoak pipeline-en barnean mantentzen ditu. EMI supresioa 40dB baino handiagoa da zonas sentikorretan.
- Gasen gestio inteligentea: Erdi sekula edo insulazio-gas garbi erabiltzen ditu nano-eskalako gas-sensorren bidez. 0.001MPa baino txikiagoen presio gorrimenak detektatzen ditu eta alerta aktiboak gertatzen dira.

Ⅲ. Kasu erabilera hondarrezkoa: Tokyo Shinjuku Underground Power Corridor
$280M land acquisition cost for traditional substation expansion, Shinjuku adopted the GIL-CT solution:
- Espazio optimizatzea: Embedded 550kV CT units within existing 3.2m-diameter cable tunnels, effectively creating three "invisible digital substations" beneath Tokyo.
- Resilience: Maintained 100% operation during Typhoon Hagibis, avoiding flood-induced outages common with surface equipment.
- Cost Efficiency: Reduced construction timeline by 14 months, lowered overall costs by 37%, and saved 1,200 tons of annual cooling energy.
- Smart Grid Enablement: CT data transmitted via tunnel fiber optics enabled microsecond-level fault localization.
Power Engineer Koichi Matsumoto: "This integration allows us to add medium-city-level capacity to Shinjuku’s financial district without acquiring a single square meter of land—what was once science fiction is now reality."
Ⅳ. Future Evolution Path
With breakthroughs in AIoT and advanced materials, next-gen systems are evolving into autonomous sensing-diagnostic entities:
- Graphene sensor coatings enabling conductor temperature profiling
- Big-data gas composition analysis for insulation lifespan prediction
- Optical quantum measurement modules achieving 0.01-class accuracy
This marks the transition from discrete monitoring devices to an underground neural network era.
