Transformer Testing Course – Lessons #20: Mechanical tests

This lesson provides an in-depth exploration of the mechanical testing procedures conducted during the Factory Acceptance Test (FAT) of power transformers. The focus is on verifying the mechanical strength and tightness of the transformer’s steel structure, ensuring it can withstand operational pressures and maintain proper sealing over its lifecycle. Key mechanical tests discussed in the lesson include:

Mechanical tests are vital to ensuring the overall structural integrity of power transformers. These tests are not only essential for confirming that the transformer can withstand operational stresses and maintain tight seals but also help to prevent potential failures in the field. By conducting these tests, manufacturers can detect issues early in the production process and take corrective actions before the transformer is delivered to the customer.

For professionals in the transformer manufacturing and maintenance industries, understanding the procedures for mechanical testing is crucial for ensuring the long-term reliability and safety of transformers.

This lesson will provide you with a comprehensive understanding of the procedures and evaluation criteria for various mechanical tests, including leak testing, pressure deflection testing, vacuum deflection, and vacuum tightness testing. Whether you’re an engineer, technician, or researcher in the field of transformer testing, this lesson will enhance your knowledge and skills in ensuring the quality and reliability of transformers.
