Safe Handling of High-Voltage Systems
In this training system the focus is on safety when working with high-voltage electric vehicles and the dangers of electric current passing through the human body. What sort of current can flow through a body in the event of a fault? What is the meaning of "single fault tolerance"? How does one protect oneself? All these questions and countless others are answered by this course.
