Defining Safe Electrical Clearances
Air gaps are used across an electrical system as insulation. The size of the air gap must provide a sufficient clearance to prevent flashover. The environmental factors of temperature and pressure will influence the size of this clearance.
This course will explain to you how we can select a safe electrical clearance in systems operating at voltage levels of up to a few thousand volts.
The course is focused specifically around transport systems where gaps will be relatively small. It does not discuss the different breakdown mechanisms we see in the much larger gaps used on the high voltage power system.
