Model Technical Specifications | Engineering — Substation Department

This intelligent assistant leverages a Large Language Model (LLM) to provide precise, context-aware answers directly from POWERGRID's official documentation.

Document Coverage:

• 📑 Model Technical Specifications — Engineering (Substation) Department, POWERGRID
• ⚡ Applicable to AIS/GIS Substations up to 765kV
• 🔄 Updated to the latest revision as on 03-May-2026.

Guidelines for Effective Use:

• Frame queries with specific equipment names and voltage class (e.g., 765kV GIS Circuit Breaker, 400kV Surge Arrester, 220kV Isolator)
• Include clause keywords for targeted retrieval (e.g., type test, insulation level, earthing, interpole cabling)
• For comparative queries, specify the parameter of interest (e.g., rated current, BIL, SF₆ gas pressure)
• Clear the chat session if responses appear off-context or drift from the query intent

  ⚠️ Responses are strictly based on the provided documentation. Always verify critical design parameters against the original Model TS before application.
