TXplore™ transformer inspection robot

Power transformers have complex internal systems that degrade over time. As a consequence, it may be necessary to inspect the internal components for signs of abnormal operation. Hitachi Energy's TXplore accomplishes an internal inspection examining the structure of the transformer without the need to remove the oil and send an inspector into the confined space of a power transformer.

Using the TXplore™ system avoids the danger of a spill when handling the oil and the risk of sending someone inside the transformer to perform an inspection. This can be accomplished during a brief outage versus conventional inspections requiring multiple days. Also, when a traditional internal inspection is complete, significant cost savings is accomplished by avoiding the oil handling and processing equipment needed to remove the oil and reprocess and fill the transformer.

TXplore service can be scheduled ahead of time to take advantage of a planned outage with little or no increased downtime. It is also possible to deploy the service team to perform an inspection when unexpected issues are encountered.
