Can dry ice clean a transformer without de-energising?
No. We only clean transformers, external or internal, once isolated and proven de-energised.
Verdict
It depends
De-energised only, always. Asset owner's safety case applies to the isolation and testing procedure.
The detailed answer
No. Whether it's external cleaning (radiators, cooling fins, bushing porcelain, tank exterior) or internal work and terminal-box maintenance, we require de-energisation first — a licensed electrical worker isolates the transformer and proves it dead, with our own lock and tag on the isolation point, before we start. We work to your asset owner's safety case and electrical authority throughout. Dry ice leaves no residue and needs no drying time, so the isolation window is as short as possible. Per-asset photo log + IR readings (where applicable) provided.
