Packing and Delivery Transformer

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.
