Power

Generation, transmission and substations, where physical access is hard.

What it solves

Inspecting a substation takes permits, clearances and a window. The camera is already there every day.

What gets measured here

Every signal, with the standard behind it

  • 95 °C

    Oil critical · 75 alert

    Transformador · punto caliente

    Winding temperature consumes service life at a calculable rate, and the system keeps count.

    IEEE C57.91

  • 720 ppm

    TDCG at condition 1 · 1,920 condition 2 · 4,630 condition 3

    Gases disueltos en aceite

    The ratio between gases tells an arc from overheating months in advance.

    IEEE C57.104 · IEC 60599

  • > 15 K

    Over the twin component · 4–15 scheduled · 1–3 investigate

    Subestación · conexiones

    ΔT over the reference on terminals, switches and busbars, classified into action bands.

    NETA MTS · NFPA 70B

  • 600 W/m²

    Minimum irradiance · below it, thermography is worthless

    Solar · módulos

    Hot spots, dead strings and shorted diodes, following the standard's procedure.

    IEC 62446-3

The full catalogue is 311 standards across fourteen domains, and it lives inside the platform — next to the field where the number goes — not in an appendix to the manual.

A concrete case

Close-up of an industrial electric motor on its base, with the terminal box in view.
Medium-voltage motor · the limit comes from the insulation class on its nameplate, not from a round number.

A motor at 68 °C can be healthy or about to fail

It depends on its insulation class and on what it is compared against. A class F motor takes what a class B does not, and the same motor at 68 °C in January and in July does not mean the same thing: what matters is the ΔT over its reference, not the absolute figure. That is why the limit is not typed in by hand — it comes from the machine's nameplate and the standard that applies to it.

  • Winding temperature by class

    IEC 60034 · NEMA MG-1

    The limit is set by the insulation class on the nameplate. A class F is not judged with a class B threshold.

  • ΔT over the reference

    NETA MTS 100.18

    The rise over the twin machine, or over itself a month ago. Above 35 °C it stops being monitoring.

  • Bearing temperature

    ISO 10816-3

    The bearing warns before the winding does. Its trend is what gives the window to act without stopping the line.

What it uses

Without getting close

Radiometric measurement is taken at a distance and without an outage, which turns a permitted inspection into a continuous reading.
