Trafol (transformer app) Live

This transformer asset management app is the only app you will ever need to manage your electrical transformer! It includes transformer oil analysis tools (dissolved gas in oil analysis (DGA)) as well as many features to store and interpret your oil analysis results. 🔬 What the app does: • DGA Calculator — assess dissolved gas in oil concentrations against IEEE C57.104-2008 condition thresholds (Conditions 1–4) and calculate TDCG • Doernenburg Ratio Method — fault type diagnosis using four standard gas ratios (R1–R4) • Rogers Ratio Method — three-ratio fault classification as per IEEE • Duval Triangle — IEC 60599 ternary plot visualisation with automatic fault zone identification (PD, D1, D2, DT, T1, T2, T3) • Oil Quality Assessment — evaluate dielectric strength, power factor, interfacial tension, acidity, water content, and colour per IEEE C57.106-2006 • Furan Analysis — 2-FAL to DP conversion per ASTM D5837 for paper insulation condition assessment • O₂/N₂ Ratio — seal integrity indicator calculated automatically 📋 Asset Management: • Manage a full fleet of transformers with detailed nameplate data (manufacturer, kVA rating, winding configuration, cooling type, tap changer, and more) • Organise oil samples by date per transformer — full history at a glance • Mark units as spare and share availability with other saVRee users via the Spare Transformer Database • All analysis methods share the same gas data — enter values once, get all results instantly 🌍 Multi-language Support: Available in English, Spanish, French, German, Portuguese, and Italian. 🧮Why engineers choose Trafol: All calculations are performed on-device — no internet connection required for analysis.
