AUSPTA have another article in APT's Industrial Electrix for Q1 2026 - 'When “Green” Runs Hot: Thermography, Harmonics and Hidden Risks in Large Solar Installations'

Walk into any modern industrial site and you are likely to find a roof covered in photovoltaic panels and a substation full of inverters humming away. On a recent thermographic inspection of a new commercial solar installation at a large mixed-use facility, that hum translated into something more worrying: cables and switchgear running so hot that you could quite literally have boiled a kettle on them.

While completing unrelated works on site, our installation and commissioning technicians happened to lean against a recently installed AC input cubicle and, if not for a layer of protective clothing, would have immediately burned their skin on the surface of the escutcheon panels.

Naturally we immediately offered to dispatch a condition monitoring team to site, an offer which the client gladly accepted, and unsurprisingly the team immediately identified components operating with temperatures well outside their design parameters. What was interesting however, is that these components were operating with load conditions well inside their design parameters.
