Solusyon sa Combined Instrument Transformer (CIT) para sa Ekonomiko & Optimisasyon sa Espasyo

​

​Challenge:​​ Ang mga substation, lalo na ang mga aging facilities na nangangailangan ng retrofit (kasama ang Gas-Insulated Substations - GIS) o bagong installation sa mga urban environment na may limitadong espasyo, naghaharap ng malaking presyon upang makontrol ang footprint at cost. Ang mga tradisyonal na separate Current Transformers (CTs) at Voltage Transformers (VTs) ay nagdudulot ng hindi epektibong paggamit ng espasyo, mataas na gastos sa materyales/installation, at komplikadong maintenance.

​Our Solution:​​ Ipapatupad ang purpose-designed, compact ​Plug-and-Play Combined Instrument Transformer (CIT)​​ solution. Ang bagong pamamaraan na ito ay nag-integrate ng CT at VT functionality sa isang single, optimized device, nagbibigay ng malaking benepisyo mula sa ekonomiko at spatial perspective.

Core Features & Economic/Space Optimization Strategy

1. ​Radical Footprint Reduction (Space Optimization):​​
• ​Single Unit Design:​​ Nagpapalit sa tradisyonal, spatially separated CT at VT units ng isang integrated device.
• ​Compact Enclosure:​​ In-engineer para sa tight spaces, ideal para sa congested substations, brownfield site retrofits (lalo na sa existing GIS bays), at greenfield projects kung saan ang lupa ay mahal o limited.
• ​Result:​​ Nakakamit ang ​50-70% reduction​ sa required installation footprint kumpara sa conventional separate units. Ito ay nagbebentahan ng valuable real estate para sa iba pang critical equipment o future expansion.
2. ​Lightweight Composite Materials (Cost Optimization - CapEx):​​
• ​Material Innovation:​​ Gumagamit ng advanced composite polymers o hybrid composites sa halip na traditional porcelain o heavy metal housings.
• ​Significant Weight Reduction:​​ Dramatically lowers the overall unit weight.
• ​Foundation & Structural Cost Savings:​​ Reduced weight translates directly to ​simpler, lighter, and less expensive support structures and foundations. This lowers both material and civil engineering costs during installation or retrofit.
3. ​​"Plug-and-Play" Installation (Cost & Time Optimization - CapEx & OpEx):​​
• ​Pre-Integrated Design:​​ Factory-assembled and tested CIT unit ensures core CT/VT alignment and calibration are complete.
• ​Simplified Site Work:​​ Reduces on-site assembly complexity and installation time.
• ​Reduced Labor Costs:​​ Faster installation translates to lower labor expenses.
• ​Minimized Downtime (Critical for Retrofits):​​ Especially vital in GIS retrofits or live substation upgrades, where minimizing outage windows is paramount for grid reliability and operator revenue.
4. ​Standardized High-Utility Ratio Designs (Cost Optimization - CapEx & OpEx):​​
• ​Limited Range of Optimized Types:​​ Instead of stocking a vast array of separate CTs and VTs, standardize on a curated portfolio of CIT designs covering the most common voltage levels, current ratings, and accuracy classes (e.g., covering 80% of typical substation requirements).
• ​Streamlined Inventory Management:​​ Utilities and suppliers benefit from drastically ​reduced SKU counts​ for instrument transformers.
• ​Reduced Initial CapEx:​​
• ​Fewer Units:​​ One CIT replaces two devices, lowering the unit purchase count.
• ​Smaller Structures:​​ See Point 2 (Lightweight Materials).
• ​Bulk Procurement Savings:​​ Standardization allows for larger volume purchases per CIT model, leveraging economies of scale.
• ​Reduced Long-Term OpEx:​​
• ​Simpler Maintenance:​​ Only ​one unit​ needs inspection, cleaning, and physical checks instead of two. Access points are consolidated.
• ​Reduced Testing Time & Cost:​​ Only ​one unit​ requires primary and secondary injection testing during commissioning and routine maintenance, effectively halving the testing time and associated labor/resource costs compared to separate CTs and VTs.
• ​Optimized Spare Holding:​​ Lower SKU count means fewer different spares required in inventory, reducing tied-up capital and storage space.
