Most of the 'relay' problems I have faced were actually human errors instead of equipment errors. Most relay tests would not catch these errors. Examples: Wrong CT/PT ratios, wrong polarity.
This course helped show how testing a relay can also catch human errors in the installation of equipment or wiring and the programming.
This course is unlike any I have ever seen. I have paid ten times the cost to attend training in person, and the training usually covers mostly theory and standards. This course actually shows you how to do real-world relay testing.
