Fleet assessment

Sixty reports, three laboratories, one budget meeting

A fleet assessment runs the DGA and oil test history you already have through RONIN by Seetalabs and returns every transformer ranked by condition, with the method behind each result, what is missing, and an action plan by window.

A paid engagement, agreed before any data is exchanged. For five transformers or fewer, Fleet DGA Triage ranks them by DGA urgency, free, in your browser.

How it works

Four steps, and the first one is a conversation

  1. Step 1 of 4

    Scope

    We agree the transformers, the data you have and the question the budget has to answer. You receive a written offer.

    before any data
  2. Step 2 of 4

    Data

    You send the laboratory files as they are, PDF, Excel or CSV, through an agreed channel. Values, units, dates and asset identity are reviewed with you before any calculation.

    reviewed with you
  3. Step 3 of 4

    Assessment

    RONIN reads each sample with the methods that apply to its fluid, signs an index where the data allows it, and names what is missing.

    method, edition, clause
  4. Step 4 of 4

    Results

    The ranked fleet, an Asset Health Report per transformer and the action plan, with the option to continue in RONIN.

What comes back

Every transformer ranked, with the reason and the clause

Worst first, with the recommended action on every row and the rated capacity by band.

How the ranking is built

Each sample is read with the methods that apply to its fluid: IEEE C57.104-2019 and IEC 60599:2022 for mineral oil, IEEE C57.155-2014 for esters, oil and paper property by property under IEC 60422:2024 and IEEE C57.140-2017. The health index is signed by the model, with its uncertainty band, or by the standards on measured values only.

Planning estimates are stated at your country's price level and are not quotations. The decision stays with the engineer responsible for the asset.
