In the transformer dehydration process, the moisture from the oil is removed and insulation is improved. Transformer oil is one of the most essential components that serves the multipurpose of insulation and cooling its parts. GNT Transformers is a leading manufacturer of all types of transformers and we provide comprehensive Transformer Dehydration service for maintaining its smooth operation and long life. By providing dehydration services, we improve the insulating properties of the oil, and dielectric strength, prevent component rusting and corrosion, and reduce the risk of electrical arcing.
Transformers are installed mostly outdoors, making them prone to moisture and water seeping into the oil. Moisture is one of the primary contaminants of oil which results in breakdown and failure of most transformers. It reduces the ability of transformer oil to prevent electrical breakdown (dielectric strength), increases the chances of short circuits by making the oil conductive, causes bushings, core, and windings to rust, and impacts the ability of oil to dissipate heat from core and windings. When moisture reacts with oil, it forms acidic liquid and sludge on its parts which further corrodes the components. Moreover, the dehydration is better than replacing the oil because it is economical. Replacing the oil requires more labour, capital and more downtime of power supply. These are the reasons why we perform transformer dehydration by employing our competent personnel and advanced processes.
Transformer dehydration can be done through various methods like hot air blowing, hot oil spray, cyclic drying, etc. But vacuum purification is the most reliable method. In this method, we use a vacuum pump to create a vacuum in the dehydration chamber where oil is contained, lowering the boiling temperature of water. The water is removed by boiling and collecting it in a condenser. For accessing this equipment in any place, we mount it over mobile trailers so it can go anywhere no matter how remote the transformer is located. Here is the list of transformers that we repair and the range of service rating and capacity:
Distribution Transformers
Power Transformers
Dry-type Transformers
Isolation Transformers
Control Transformers
Furnace Transformers
Servo Voltage stabilizers
GNT Transformers is one of the most trusted manufacturers of transformers that provides comprehensive transformer maintenance services. We have a dedicated team to schedule the maintenance of transformers that we provide to our customers, and our quality engineers regularly inspect and optimize the load. During maintenance, we provide a backup transformer so that the power supply is not interrupted. Apart from dehydration, we provide complete oil filtration service also to clean the sludge, impurities and other solid contaminants.
