Transformer oil test reader for commissioning and service work

Transformer Oil DGA Reader is an Android field aid for oil-filled transformers. Type the lab page or calibrated portable-kit readings once, then review dielectric breakdown, water, percent saturation, IFT, acid, color, Duval triangle, Duval pentagon, C57.104 status, and per-serial drift in one place.

Full oil page
Breakdown, water, temperature, IFT, acid, color, gases, reviewer note, and export all stay on the same serial.
Duval geometry
Triangle 1 names the gas pattern, Triangle 4 and 5 refine the cases they are meant to refine, and the pentagon cross-checks the result.
C57.104 status
Derived condition logic separates gas level, rate, and oil-line grading so a fast rise does not disappear inside a single label.
Field exports
Save per-unit PDF, CSV, field-card PNG, and fleet CSV files locally, then share through Android only when you choose a destination.

Price

Free for three transformers. Paid access unlocks unlimited units, clean exports, and saved presets through Google Play Billing: $19.99 monthly, $199 annual, or $499 lifetime.

Scope note

This app does not measure oil or gas and is not an energize-or-not ruling. The lab or calibrated kit is the instrument, and a qualified reviewer makes the energization call. Verify every value and result before energizing.

FAQ

What does this app do? It grades a transformer oil page, plots gases on Duval charts, names the likely fault zone, shows C57.104 status, computes drift, and exports a per-unit result.

Is it offline? Entry, math, plots, local storage, and exports run on-device with no signal. Play Billing restore and Android share targets may use platform network access when available.
