Transformer School for Electric Line Workers

Posted By IAMU, Wednesday, December 5, 2018

The upcoming Transformer School workshop is open to electrical workers in transmission, distribution, substation, and Power plants.  The material is applicable to workers ranging from new apprentice as an in-depth look at the transformer material to journey level as a refresher for those that haven’t had the work type needed to keep their memory sharp.  I will be covering material from beginning to end while receiving supplemental assistance from Dave Link, Bob Hiatt, and Jim Thompson.  Information will be delivered via printed diagrams, verbal explanations, and by building indoor models on the training poles.  Below is what the course agenda will look like.
