VPS in the EU · GDPR Your data does not train the model

Ronin AI does more than apply a trained model to laboratory data. It selects applicable diagnostic methods, keeps uncertainty distinct from condition, and connects findings with the asset's history. Natural and synthetic esters have dedicated assessment routes rather than inheriting a mineral-oil model.

THE RONIN AI WORKFLOW

From laboratory files to a reviewed maintenance plan.

Prepare the data, interpret it for the right fluid, examine its history and review the next actions. This is the workflow of the forthcoming Ronin AI release.

  1. STEP 01

    Import and review

    Upload supported laboratory files and let the parser prepare the measurements. Review values, units, sample dates and asset identity before submitting the analysis.

    What needs checking?

    Check field mappings, fluid identity and flagged or missing measurements against the source report. Ambiguous layouts need correction; scanned documents depend on OCR availability and source quality.

  2. STEP 02

    Diagnose for the fluid

    Read applicable deterministic diagnostics alongside the condition assessment. Mineral oil, natural esters and synthetic esters follow dedicated assessment routes, not one universal model.

    Where does uncertainty fit?

    Where available, probabilistic calculations show how classifications respond to measurement uncertainty. The trained health-index model is used where applicable. Neither an index nor a simulation frequency is a calibrated probability of failure.

  3. STEP 03

    Read the trends

    Examine the asset history, changes in diagnostic findings and eligible gas-generation trends. A single sample cannot show how the evidence has evolved.

    Which comparisons are meaningful?

    Check sample dates, units, fluid and assessment method before comparing results. Missing measurements are not zero, and a change in method must not be mistaken for physical deterioration.

  4. STEP 04

    Review the Action Plan

    Examine proposed actions linked to diagnostic findings and evidence gaps. Review timing and stated cost assumptions with the engineer responsible for the asset.

    Who makes the decision?

    The Action Plan supports maintenance review. It does not issue autonomous operating instructions or optimise decisions from a claimed probability of failure. Loading, criticality and site constraints remain part of engineering judgement.

  5. STEP 05

    Share the evidence

    Prepare an Asset Health Report or Action Plan for review, and export selected analysis data to PDF or Excel. Keep findings connected to the available evidence and its limitations.

    Which outputs are included?

    Asset Health Report, Action Plan and selected analysis exports. A dedicated fleet health report is not included in the forthcoming release scope.


What you get

What changes in Ronin AI

The capabilities below describe Ronin AI in release preparation, not the earlier application. HAKUTAKU advisory and a dedicated fleet-report renderer are not included in this feature list.

01

Automatic data preparation

Import supported laboratory files, preserve source values and review field mappings, units and asset associations before submitting analyses.

02

Fluid-specific diagnostics

Use applicable Duval and standards-based methods for mineral oil and supported ester families. The mineral-oil ML model is not reused as an ester-trained model.

03

Evidence-led Action Plan

Review actions connected to findings, with dates, references and explicit cost bases where available. Recommendations support approval by the responsible engineer.

04

Trend analysis

Read gas levels and eligible trends together. Missing values are not plotted as zero, and a change in assessment method is not presented as physical deterioration.

05

Condition in context

Organise assets and examine assessed condition alongside evidence coverage. Prioritisation still requires the consequences of failure and your operational context.

06

PDF and Excel export

Share an Asset Health Report or Action Plan, and export analysis selections to PDF or Excel. A dedicated fleet health report remains outside the current release scope.

Evidence coverage

Data quality determines what can be concluded.

Collect measurements appropriate to the question and asset. Ronin AI separates the input requirements of its trained model from the applicability rules of deterministic methods. Reducing input count is not a reason to omit a necessary test.

Gas evidence
DGA
Dissolved gases describe chemical evidence of thermal and electrical activity. Interpretation depends on the method, fluid and sampling context.
Fluid condition
Oil tests
Oil tests address dielectric and physicochemical condition. Use fluid-specific interpretation and retain the test method, units and sampling date.
Asset history
Context
Loading, fluid identity, maintenance and sampling history help put the measurements in context. Compare results only when their methods and evidence support the comparison.
Dissolved gases The core diagnostic signal
H₂ hydrogen CH₄ methane C₂H₆ ethane C₂H₄ ethylene C₂H₂ acetylene CO carbon monoxide CO₂ carbon dioxide
Oil quality Condition of the insulating oil
Breakdown voltage Water content Acidity Interfacial tension
Nameplate Context for the score
Rated power (MVA) Voltage (kV) Manufacturer Year

Data coverage is not diagnostic accuracy. Ronin AI distinguishes missing measurements, method eligibility and uncertainty, and can withhold a result when the available evidence does not support it.


Scale and coverage

Fluid and operating duty change the interpretation.

A laboratory report is the starting point, not the whole context. Fluid type, transformer duty, sampling conditions and data quality determine which methods apply.

Method · interpretable AI, anchored to the standards

An open box, not a black one.

Ronin AI combines deterministic diagnostic engines and probabilistic uncertainty analysis with a trained health-index model where applicable. These components answer different questions: what the evidence indicates, how stable the classification is, and how the assessed condition changes. The method used and its limitations matter as much as the number.

The reference framework

The international reference for the transformer health index and fleet prioritisation. RONIN's model is anchored to it, so the output maps back to a published method.

Method and applicability must be checked
IEC 60599:2022

DGA interpretation

The Duval Triangle interpretation of the dissolved gases follows IEC 60599, so the fault type on the report is one an engineer can independently check.

AI governance

AI governance requires a documented intended purpose, validation, oversight and lifecycle controls. Ronin AI's architecture supports that work; software features alone do not establish AI Act conformity or ISO/IEC 42001 certification.

No certification claim
Model performance and its limitations
80%historical model R²
Understanding model metrics

A model metric is not diagnostic certainty.

The historical R² figure describes the fit of one trained health-index model to its evaluation targets. It is not the accuracy of the complete Ronin AI system, a probability of failure, or the chance that an individual diagnosis is correct. A higher R² does not automatically imply overfitting: that requires evidence from independent validation.

Ronin AI separates measured inputs, diagnostic rules and uncertainty assumptions. A result can be computable yet unsuitable for interpretation. Missing evidence, method disagreement and fluid-specific applicability therefore remain visible instead of being compressed into one reassuring score.

makoto, sincerity. A samurai does not promise. Saying and doing coincide. That is the standard we hold the number to.
The scale

Read the index with its assessment method.

These are the mineral-oil model bands, assigned after rounding for display. Deterministic ester assessments use the producing engine's condition class and scale. Neither scale represents probability of failure.

Data handling and deployment
Your data, handled straight

Critical-infrastructure data deserves plain answers.

No dark patterns and no fine print. Here is exactly where your data lives, what it is used for, and how it is kept apart.

Hosted in the EU

Your data sits on a VPS in the European Union and is handled under the GDPR.

Not used for training

Your DGA, oil and asset data are never used to train or tune the model. Your fleet stays yours.

No user tracking

No behavioural tracking. Account data is minimal: name, email and an optional company. No photos.

Isolated per customer

Transformer records can contain commercially or operationally sensitive information. Access permissions, customer separation and retention requirements should be agreed for the deployment; asset data should not be assumed non-sensitive.

Secure data transfer

The application uses HTTPS for data transfer. Hosting, access controls and the boundaries of backend services should be reviewed against your organisation's security requirements.

Firewalled by default

Access is firewalled and the scoring service is reachable only through the application, not directly.


Pricing, in plain sight

Pay for the decisions you make. Nothing else.

No hardware to buy, no capacity licence to negotiate before you can start, no hidden line items. Here is how it works, in the open, instead of a "contact us for pricing" wall.

01

Pay as you predict

A usage model: you pay for the predictions you run, one per asset assessed. No sensor, no gateway, no subscription for capacity you never use. Start with a single transformer.

02

Volume brings the unit cost down

The more assets you assess, the less each one costs. A large fleet scored in a batch is priced well below the same assets one at a time, so ranking a whole population stays affordable.

03

Higher plans on request

Running continuously across a very large fleet, or need dedicated terms? Higher-volume plans are arranged directly, sized to your fleet and cadence, not forced into a tier that does not fit.

04

White-label for partners

Oil-treatment, testing and service companies can resell the health index and reports under their own brand. A software add-on to the sampling you already do, arranged on request.

$30k to $50kper hour of unplanned outage
Scoring an asset with RONIN costs a small fraction of a single hour of unplanned downtime, and a rounding error against a transformer failure that runs into the millions with a replacement lead time measured in years. The question is not what a prediction costs. It is what one missed failure costs.

Transparent by design. The free account runs a guided demo before any commitment. No sales calls, guided by AI.


Answer-first · FAQ

The product questions engineers actually ask.

How do I get my data in, and from which lab? +
Ronin AI adds automatic preparation of supported laboratory files and documents. Review extracted values, units, dates and asset identity before analysis. Unrecognised layouts, ambiguous fields and poor scans can require manual correction.
What transformers does RONIN cover? +
Ronin AI covers mineral oil and supported natural and synthetic ester diagnostic routes. Applicability depends on the declared fluid, equipment and available evidence; transformer rating alone does not establish coverage.
What is in a per-asset report? +
The Asset Health Report brings together measured evidence, diagnostic findings, assessment method and data limitations. The Action Plan is a separate decision-support document. PDF and Excel exports serve different reporting needs.
How does RONIN handle missing parameters? +
Ronin AI checks whether the trained model can be used. Missing gas measurements can exclude that route; a deterministic assessment may be used where applicable and is identified separately. If no supported result is available, the system does not present an invented score.
Does the 80% mean RONIN is only 80% correct? +
No. That historical R² relates to one trained model, not the complete Ronin AI architecture. Deterministic classification, measurement-uncertainty calculations and model-based assessment need separate validation. A higher R² alone proves neither better generalisation nor overfitting.
How is RONIN different from a DGA calculator or an online monitor? +
A useful free calculator answers one diagnostic question. Ronin AI connects methods, uncertainty, longitudinal asset evidence, Action Plan and reporting. It complements laboratory testing and online monitoring rather than replacing the measurements they provide.
