Transformer & energy monitoring

An ageing EHV transformer can carry a developing fault for months before the failure becomes obvious. Hotspot temperature, dissolved gases, oil condition, and electrical load are usually measured in separate routines, leaving operators without one continuous health record.

Outcome
Failure predicted; loading headroom released
One accountable stack

We specify the field hardware and the software around the same asset model, with one engineering team responsible for the result.

The InfiIoT software layer

What the platform does with all that hardware data.

Live per-transformer twin

Oil, winding, gas, and load measurements share one time-aligned asset view instead of separate quarterly spreadsheets.

Thermal ageing model

IEEE C57.91 loss-of-life calculations use measured hotspot and load data to estimate available loading headroom.

DGA fault intelligence

Duval-triangle classification and gas-trend rules separate an emerging condition from one that needs immediate action.

Regulator-ready reporting

Scheduled health and loading reports use the same traceable history reviewed by utility teams and CEA processes.

Hardware and software, one proposal.

Bring the asset, interfaces, and operating constraint. We will map the likely bill of materials and the first platform workflow.

Connected-product assessment

Bring one product. Leave with a clear next step.

Use 30 minutes to test the fit around one product and one blocked decision. If there is a fit, we will outline the two-week Product Blueprint.
