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. 

Attendees will have access to the following sections of the course: 

Instructor-  Ian Cotton

Technical Director
Ian is the Technical Director of aerospaceHV. He has vast experience in the development of safe high voltage systems for use in aerospace applications having been involved in design and test work for systems used on the Boeing 787, Airbus A350 and the E Fan X project that targeted a 3kV operating voltage. He is a member of SAE and ASD standards committees that are developing the next generation of high voltage standards. 

Instructor-  Juliana Beça

MSc, PhD
Juliana is working in the development of the company’s portal with essential courses, training for aerospace and automotive companies and partial discharge testing. Juliana completed her PhD in HV Engineering at The University of Manchester.
