We have just completed our new film series "easily explained" on the ungrounded system, the IT-system. Each series consists of a number of short films or clips, the aim of which is to make a complex topic easy to understand so that we can reach a greater target audience and educate them on electrical safety issues.
The first series consists of three clips - one explaining the advantages of an IT-system, the second describes what happens in an IT-system in the event of an insulation fault and the last one explains how to locate an insulation fault.
Series on other electrical systems will follow.
