RONIN AI is a transformer health index software. It calculates a health index built on CIGRE TB 761 from your existing DGA and oil test data, then ranks an entire fleet by failure risk so you fund the maintenance that matters first. The score comes from an interpretable machine-learning model anchored to the CIGRE standards, not a black box. No sensors to install, no IT rollout, results in seconds.

The status quo

Unplanned downtime is the heaviest financial weight in energy.

Transformer fleets are managed on assumptions, not data. Too many assets, too little time, and diagnostic reports that sit in spreadsheets instead of driving decisions. Ageing infrastructure and a shrinking expert workforce have made reactive maintenance untenable. "Old" is not the same as "at risk", but most fleets still spend as if it were.

01
The data is trapped in Excel.

Lab reports arrive as spreadsheets and PDFs, then stall. The signal you paid for never becomes a decision.

02
The expert is rare and expensive.

Reading DGA correctly takes a specialist most teams no longer have in the room.

03
Maintenance is reactive.

Budgets follow age or failure, not actual risk. The wrong transformer gets the attention.

Fewer inputs, lower cost

Every parameter you measure has a price.

Every parameter in a health assessment has a cost: a sensor to fit, a lab test to run. RONIN's model distilled the 14 that carry the signal, out of 60+, so you get a dependable health index without paying to gather data you do not need. And when some are missing, RONIN still answers, at a stated, lower confidence, instead of stalling. The score returns in about 6 seconds.

One seventh of the data, so you pay to collect only what carries the signal. Missing a few? A stated, lower-confidence score, never a refusal. About 6s.

Confidence is always shown, never silent. Fewer inputs means a lower, declared confidence, not a stall and not a false certainty.

Inside the product

From substation data to a decision.

The lab results you already have, turned into a fleet ranked by risk. The Prediction List is where a whole fleet becomes a ranked worklist: green is healthy, red is at risk, and every asset carries its health index, date, type and area. This is the actual RONIN interface, not a mock-up of one.

What it changed

The challenge the customer brought. The result RONIN found.

Two anonymised programmes, told as the customer stated the problem and what the health index made possible. Sectors only, no names.

Power generation · utility

An ageing GSU fleet, and no way to rank it.

The challenge: a generation utility with an obsolete generator step-up fleet could not tell which units actually carried the risk, and kept spending on the wrong ones.

$4M

ineffective maintenance actions found
2 yrs

A 4-year health-index trend flagged the risk in time for a one-week planned outage, instead of an unplanned failure and a two-year replacement lead time.

Steel · electric arc furnace group

Over 100 assets, one budget, no priorities.

The challenge: a steel group running electric arc furnaces (over 1.1M tonnes a year) needed to know where the reliability budget should go across a large, mixed fleet.

Interpretable AI, anchored to the standards

Built on international standards for critical infrastructure.

RONIN's score comes from an interpretable machine-learning model anchored to CIGRE TB 630 and TB 761, with the standard clause shown next to every result. The trust comes from interpretability and standards, not from hiding the AI. An open box, not a black one.

80%R² · by design
The honest number

80% is an R², and pushing it higher would be a lie.

The 80% is the R² (coefficient of determination) of RONIN's health-index model, an interpretable machine-learning model anchored to CIGRE TB 630 and TB 761. It is high for a model trained on real, messy, cross-utility data. Forcing it toward 85% or more would mean overfitting the test set, a number that looks better on a slide and performs worse on your fleet.

The reason to trust it is not the number. It is that the model is interpretable and tied to published standards: every score carries its sub-scores, its Duval interpretation and its clause. The model compensates for missing parameters. It does not mask poor-quality data: good data in is still a precondition, not a variable we pretend to fix.

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

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

Each customer runs on a separate domain, accessible only to the owner. Asset data is non-sensitive by design.

Encrypted, everywhere

Encryption at the highest standard, everything over HTTPS. The ML service is never exposed to the internet.

Firewalled by default

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


For oil-treatment and service companies

Resell the decision, under your own brand.

If you already run oil treatment, testing or field service, RONIN becomes a diagnostic service you sell to your own clients. You bring the samples and the relationship; RONIN turns the data into a health index and a ranked fleet your customer can act on. A software add-on, no hardware to stock.

Seetalabs is founder-led and lean by design, backed by a deliberate network of power engineers, transformer testing specialists and utility asset managers across Europe, Asia-Pacific and the Americas.

By 2030, agents will read your fleet for you. The ones worth trusting will run on real field data from real equipment, not on headlines.

Answer-first · FAQ

The questions engineers actually ask.

What is a transformer health index? +
A transformer health index is a single score, usually 0 to 100, that summarises the condition of a power transformer from diagnostic data such as dissolved gas analysis (DGA) and oil quality. It lets asset managers compare and rank many transformers by risk instead of judging each one in isolation. RONIN AI calculates this index on a method built on CIGRE TB 761.
What does the 80% mean, and is RONIN a black box? +
The 80% is the R² (coefficient of determination) of RONIN's health-index model, an interpretable machine-learning model anchored to CIGRE TB 630 and TB 761. It is high for a model trained on real, cross-utility data. Pushing it toward 85% or more would mean overfitting, so we do not. RONIN is not a black box: the model is interpretable and every score carries its sub-scores, its Duval interpretation and its standard clause. The antidote to distrust in AI is interpretability and standards, not pretending there is no AI.
Does RONIN AI need sensors or new hardware? +
No. RONIN works from the DGA and oil test data you already collect. You download a guided template, fill in your results and upload it. There is nothing to install on the transformer, no integration project and no IT rollout. This is the core difference from online monitors, which require a sensor per asset.
Where is my data stored, and is it used to train the model? +
Your data is hosted on a VPS in the EU and handled under the GDPR. It is not used to train the model. There is no user tracking. Account data is minimal (name, email, optional company) and asset data is non-sensitive. Each customer runs on a separate domain accessible only to the owner. Everything is over HTTPS with encryption at the highest standard, the ML service is not exposed to the internet, and access is firewalled.
What is CIGRE TB 761 and is RONIN compliant? +
CIGRE Technical Brochure 761 (WG A2.49, 2019) is the international reference for assessing transformer condition and prioritising a fleet. RONIN's scoring method is built on and aligned with TB 761. It is a technical brochure, not a certifiable standard, so RONIN describes itself as methodologically aligned, not "certified".
What data do I need to get a health index? +
Key dissolved gases (hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide), oil quality parameters, and basic nameplate data (rated power, manufacturer, year). RONIN's model distilled the 14 parameters that carry the signal out of 60+, because every extra parameter is a sensor to fit or a lab test to pay for. If some of the 14 are missing, RONIN still returns a health index at a stated, lower confidence, never a silent guess and never a refusal. It compensates for missing parameters but does not mask poor-quality data.
How is RONIN different from a DGA calculator or an online monitor? +
A DGA calculator types a single fault from gas ratios. An online monitor streams data from a sensor you buy and install. RONIN does neither: it turns existing data into a health index and a ranked fleet, so you know which transformer to fix first. Everyone sells the sensor. RONIN sells the decision.

Pricing

Pay for what you assess. Nothing you do not.

Usage-based and transparent. No hardware to buy, no hidden line items, and no opaque enterprise quote you have to chase.

01

Usage-based

You pay for the predictions you run, the assets you actually assess. No hardware, no seats you do not use, no hidden costs.

02

Volume discount

The more assets you assess, the less each one costs. Scoring a whole fleet is cheaper per asset than checking a single unit.

03

Higher plans and white-label

Larger volumes, partner and white-label terms are available on request, on the same transparent, usage-based basis.

The cost is a fraction of a single unplanned outage. One hour of unplanned downtime runs $30-50k, and a transformer failure runs into the millions, as this page already shows. A health index that tells you which unit is at risk pays for itself long before that.

No "contact us" wall. You see how it works, and try it free, before anyone asks you for a number.
