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
