Oil Tank:

1. The oil tank is a transformer housing containing the iron core, winding and transformer oil.

2. The corrugated tank structure is fully sealed, and the corrugated will expand and compress with the increase of oil, isolating the transformer from the atmosphere and preventing oil deterioration and moisture. After oil removal, rust removal and phosphating treatment, the surface of corrugated oil tank is coated with rainproof paint. Moisture and salt spray.

How to Reduce Transformer Losses
Transformers are widely used in electric power systems to transfer electrical energy from one circuit to another. However, due to various factors such as resistance, eddy currents, and hysteresis, they can experience energy losses, which decrease their efficiency and increase operating costs. In order to optimize transformer performance, it is critical to understand how these losses can be minimized. In this blog, we will discuss some strategies for reducing transformer losses.
1. Choose the right core material
Using the right core material can greatly reduce transformer losses. Transformer cores are made from magnetic materials such as iron or steel, which can be laminated to reduce eddy currents. High-quality cores that are designed for low loss can improve transformer efficiency.
2. Optimize the winding design
The winding design is another factor that can affect transformer losses. A proper winding design with the right number of turns, correct wire gauge, and uniform winding distribution can minimize losses due to resistance. This can be achieved through careful analysis and simulation of the transformer design.
3. Use high-quality insulation
The insulating material used in the transformer plays a critical role in reducing losses due to hysteresis and eddy currents. High-quality insulating materials such as mica and varnish can provide better insulation and reduce energy losses.
4. Maintain proper cooling
Transformers generate a lot of heat during operation, and overheating can increase energy losses and reduce transformer life. Proper cooling systems such as fans, radiators, or oil-cooling can remove excess heat and ensure efficient operation.
5. Reduce load losses
Load losses occur when the transformer is under load, and can be reduced by improving the power factor, reducing voltage drop, or choosing the right transformer size. Monitoring load losses and optimizing load factors can significantly reduce energy consumption.
In conclusion, transformer losses can be reduced through careful selection of core materials, optimization of winding design, use of high-quality insulation, proper cooling, and load management. By implementing these strategies, transformer efficiency can be improved, resulting in reduced energy consumption, lower operating costs, and increased reliability.

Why Do Transformers Fail?

An electrical transformer can blow for a variety of reasons and can cause an explosion or fire. Causes of transformer explosions could include:

· Lightning strikes

· Overheating

· Wear and corrosion

· Damage to the electrical system anywhere along the line

· Failed safety devices and power surges

· Foreign objects or animals getting into the transformer

· Moisture

When a transformer fails, it will usually result in a loud boom, a power outage, and a fireball that creates a large plume of smoke.

The final assembly begins with the removal of the core and coil assembly from the vapor phase. All internal components are re pressed under the pressure specified by the project, and now the excess water has been removed to ensure the tightness. The metal and fiber nuts are tightened or tightened as required, and the electrical clearance is verified again.

 

The core and coil assembly are placed in the tank, which is filled with oil to prevent exposure to air, and a cover assembly is added to connect with the sleeve. Once the enclosure is welded and leak checked, the galvanized radiator is assembled to the tank, the unit is drained, and the transformer is vacuum filled for final testing. During this period, the control box and any other customer specified monitors and components are installed and connected. All external welded components shall be installed to ensure correct installation to the tank and removed prior to the completion of the factory acceptance test of the transformer.

 

Routine tests of transformer include:

1.Winding resistance test of transformer

2.Transformer ratio test

3.Transformer vector group test

4.Measurement of impedance voltage/short circuit impedance (principal tap) and load loss (Short circuit test)

5.Measurement of no-load loss and current (Open circuit test)

6.Measurement of insulation resistance

7.Dielectric tests of transformer.

8.Tests on on-load tap-changer.

9.Oil pressure test on transformer to check against leakages past joints and gaskets
