Power Transformers - Factory Acceptance Tests (FAT) (PowerPoint PPT)

This program covers the Theory, Operation, Maintenance, Diagnosis, and Testing of Power Transformers and Auxiliary Equipment. The complete Transformers program consists of 12 modules (individual PowerPoint presentations).

This document refers to the training module 9 only: Factory Acceptance Tests (FAT). Specific topics covered include:

•  Test Classification and Conditions
•  Type Tests
•  Routine Tests
•  Special Tests
•  Bushings
•  Dry Transformers
•  Oil Testing

Upon the successful completion of the full Transformer Operations program (all 12 modules), you will be able to:

•  Operate, maintain, troubleshoot and test power transformers in a professional manner
•  Discuss the basic concepts of transformer covering the main electric parameters and laws, magnetism and electromagnetism, Lenz and Faradays Laws, circuits, star and delta connections, theory, the role of transformers in power systems, standards, regulations and voltages
•  Identify the various types and construction of transformers
•  Describe special transformers as well as enumerate transformer components and materials
•  Determine cooling of transformers, transformer performance and electrical parameters
•  Recognize transformer faults and employ proper protection, operation and factory acceptance test (FAT)
•  Install, test and commission transformer efficiently

This module delves into the critical parameters and conditions required for conducting Factory Acceptance Tests (FAT) on power transformers. It emphasizes adherence to IEC standards, ensuring that testing procedures are performed under precise ambient conditions. The PPT outlines the classification of tests, including type tests, routine tests, and special tests, providing a comprehensive understanding of each category.

Detailed explanations of routine tests such as no-load harmonics, impedance voltage drop, and dielectric tests are included. Special tests, which require agreement between the client and manufacturer, cover aspects like dielectric strength and zero sequence impedances. The module also addresses the importance of oil testing, including chemical and physical properties, interfacial tension, and viscosity, highlighting their impact on transformer performance and reliability.
