  3. Analyze the operation of three-phase transformers
    Assessment Strategies
    by creating a drawing with written explanations analyzing three-phase transformer operation
    Criteria
    drawing labels the parts of a three-phase transformer
    drawing shows a blowup of the data plate and has all information clearly presented

    written explanation details the purpose of each piece of data on the data plate
    written explanation describes operation of the three-phase transformer
    written explanation describes how voltage and current puts could be or would be changed

  4. Create a remedy table for some of the most common single and three phase transformer problems
    Assessment Strategies
    by creating a problem/cause/solution table
    Criteria
    the table shows at least three of the most common transformer problems for single-phase transformers
    the table shows at least three of the most common transformer problems for three-phase transformers
    the table lists common causes for each problem
    the table shows common causes in "general" order of likelihood with the most likely being #1
    the table shows possible solutions for each cause shown
    the table shows suggested solutions in relative order of ease to perform with the easiest being #1
