Distribution Transformer DGA Checker
IEEE C57.104 dissolved-gas screening with key-gas fault pattern for a distribution transformer.
DT oil samples rarely get lab-grade interpretation — paste the ppm values and get the screening verdict DISCOM labs would give. For sealed units, any acetylene or doubling hydrogen between samples is worth a tanker visit.
IEEE C57.104 Condition-1 screening with key-gas pattern matching for this distribution transformer. Any acetylene above ~1 ppm deserves attention — it only forms in arcs. Trends beat absolutes: resample in 30 days; doubling gas is an active fault regardless of level.
Planning estimate only — interconnection, protection settings and compliance must be reviewed and signed off by a licensed electrical engineer and your utility before energisation.

Frequently asked questions
What does dissolved gas analysis tell you about a transformer?+
Oil dissolves the gases faults generate, each fault type with a signature: hydrogen from partial discharge, ethylene from hot metal, acetylene only from arcing, CO from cooking paper. A ₹5,000 oil test reads the transformer's internal health without opening it — the cheapest diagnostics in the substation.
Which DGA result demands immediate action?+
Acetylene above ~1–2 ppm, or any gas doubling between samples. Acetylene forms only above ~700°C — essentially arcing — and an active arc escalates on its own schedule, not yours. The screening verdict here flags it red; respond with resampling, loading review and expert analysis.
How often should transformer oil be tested?+
Annually for distribution and healthy power transformers; quarterly to monthly once any gas trends upward; immediately after through-faults, alarms or relay operations. The trend is the diagnosis — single samples only screen, which is exactly what this tool does.
Can this screening replace lab Duval-triangle analysis?+
No — it's the first read, applying C57.104 limits and key-gas heuristics to flag what deserves expert attention. Duval triangles, ratio methods and gassing-rate analysis on accredited lab data make the formal diagnosis. Screen here, escalate with confidence.
