In principle, yes – TOR-5 can be transferred from one transformer to another, but this is not its typical or most effective mode of use. The system is designed for permanent installation so that long-term trends and historical data are preserved. Moving it frequently breaks continuity, requires flushing, air removal, and re-commissioning each time, which reduces diagnostic value. Mounting on a wheeled trolley is technically possible for temporary campaigns or trials, but in practice portable analyzers are better suited for that role, while TOR-5 shows its real benefit in fixed installations on critical transformers.
