TRANSFORMER TRY-OUT SYSTEM
TRANSFORMER TRY-OUT SYSTEM
On-line Vacuum Dry-out units allow drying of transformer windings while the transformer remains in normal service. Maintaining low moisture levels in the cellulose ensures the transformer is less likely to fail due to shock loadings, such as lightning or through faults, and insulation material is not degraded through chemical reaction with moisture.
ESI operates a Transformer Oil PCB Dechlorinating and Recycling Facility in the ACT as well as an itinerant service in some Australian States and Overseas. All plant operations are operated via a computer controlled SCADA system which ensures maximum protection to the Operator and Environment and to entire process also.
As fully licensed PCB Waste Transport Operators, ESI can provide a one-stop oil exchange service utilizing our dedicated tanker, filtration and vacuum filling equipment operated by specialist staff.
ESI own the exclusive rights to Velcon Transformer Oil Filter Technology in Australia. Over the past few years ESI have developed small portable transformer drying systems utilising Velcon’s Superdri dissolved moisture removal cartridges to dry the transformer cores online. The advantages of this system includes:
- The transformer can be left in the service during the entire operation.
- No mechanical stresses are imposed on the insulation or tank.
- Core shrinkage is minimised as water is replaced by dry oil on removal.
- Drying is gradual and can be monitored through on-board metering.
