TRANSFORMER OIL RECLAMATION Regeneration of transformer oil is energy efficient and less expensive today than refilling an older transformer with new oil. Further, it must be appreciated that simply replacing poor quality oil with newer or reclaimed oil is not the answer, as the oil will in turn, rapidly deteriorate due to re-contamination by internal components of the transformer.
The filter medium has the capacity to be reactivated and reused for up to 3 years before the medium requires replacement. ESI has been regenerating transformers and transformer oil in Australia for over a decade and have begun regenerating waste transformer oil onsite as mines, industrial clients and utilities see an area where they are able to reduce their carbon emissions and reuse a valuable commodity to beneficial reuse. Most of the contaminants in oil, including water, are polar in nature and are therefore easily adsorbed.
Regeneration, degassing and reactivation operations are all controlled by a Programmable Logic Controller (PLC) and monitored by a computer, which is located within the plant. This high degree of automation ensures a maximum safety, reliability and simplicity of operation. All vital operating parameters are read, monitored and adjusted according to program, and stored on hard disk for retrieval as and when required.
SUMMARY All ESI regeneration plants offer a high degree of reliability with respect to spillage protection during operation. Plant is manned at all times while operational. Any oil leakage from various interface devices such as relief valves, de-aerators, vacuum pumps etc, is monitored by level sensing devices and any spillage is contained within the fully bunded plants. If there is an indication of an oil spillage, the plants will shut down immediately and automatically
Oil Processing in Energized Transformer
NEW COMPACT MOBILE REGENERATION PLANT, THIS UNIT IS ALSO ABLE TO REGENERATE THE TRANSFORMER OIL WHILE ENERGISED LIKE THE LARGER PLANT THIS PLANT IS ABLE TO GET INTO AREAS THE LARGER PLANT CANNOT ACCESS FROM A TECHNICAL PERSPECTIVE THE UNIT OPERATES EXACTLY THE SAME BUT IS DESIGNED FOR THE SMALLER TRANSFORMERS
