Four transformers in Poor. Budget for two. Which two?

Lead time for a new power transformer: 128 weeks, 144 for a generator step-up. Wood Mackenzie, Q2 2025

Every sector loses a transformer in its own way: a heat, a feeder, a warranty. RONIN by Seetalabs reads the oil reports your fleet already produces and returns each unit's condition with the clause behind it. Criticality and budget stay yours.

RONIN gives the condition and the clause. The priority is yours: criticality and budget never come from the oil.

Steel, paper, cement and mining

You cannot stop the furnace to find out which transformer is next

RONIN reads the oil reports of every furnace and substation transformer and says which unit the evidence points to, early enough to plan the stop in your window, not in the middle of a heat.

In one steel plant the stop came from a reading, not from a failure: a wrong laboratory value, a quiet DGA, and a rebuilt trend that caught the decline in time to plan it.

How the plant fleet is read

Units are ordered by measured condition, not by nameplate year. Each gas is read against the change tables of IEEE C57.104-2019 across sampling dates, so a unit whose gases are rising moves up the list as soon as its results are loaded.

For loading questions, the free Moisture and Loading and Site Climate tools apply IEEE C57.91-2011 and IEC 60076-7:2018 to your own values.

Utilities, grid and generation

Several laboratories, one budget, and 144 weeks for a new step-up unit

RONIN reads every laboratory the same way and ranks the fleet by what the latest results say, with the rated capacity by band and the reason for each position.

How the fleet is ranked

You build the fleet by hand from the transformers you choose. Each unit carries its latest index, band, DGA Status and the window of its first action; the fleet view adds the MVA in Poor or Very Poor over the rated total.

The health index describes condition. Network role, criticality and replacement constraints are yours to add, and that is where priority comes from.

Transformer manufacturers and OEMs

You test the unit at the factory, then lose sight of it in the field

The commissioning oil sample becomes the first point of a trend, and every field sample is read against it with the same methods on every site.

What a partner builds on

Method, edition and clause on every reading; founder-owned technology and IP; RONIN software registered in the Italian public software registry since 2019; Seetalabs, a registered European trademark. Integration and white-label terms are agreed case by case.

Laboratories and service companies

If you test or service transformers for others

Your results or your recommendation, with an independent, clause-cited reading next to them. RONIN inside your own service.
