Objectives
Describe the different components of a transformer, explain how a transformer operates to give a desired voltage for transmission or consumption, identify different types of transformers, and describe the relationship between primary and secondary voltages and transformer turns ratio.
Identify different types of transformers based on how they work; recall what affects the accuracy of potential transformers, or PTs, and current transformers, called CTs; and explain the functions and design characteristics for both PTs and CTs.
Identify why transformers need cooling systems, recall the various methods used to cool a transformer, identify transformers based on their cooling methods, and explain the operation of cooling systems in different transformers.
Recall safety precautions when working with a transformer, recall troubleshooting techniques, identify causes of transformer failure, and identify the failure detection or prevention tests.
Describe how to remove a transformer from service, identify the basic steps required to isolate plant main and auxiliary transformers, describe what personal protection grounding is and identify the steps to install and remove it, and identify the steps to return a transformer to service.
