When a separating transformer is used, there is no conductive connection between the primary circuit ("ring main") and the secondary circuit ("consumer circuit"). There is no voltage between the consumer circuit and earth. When a person touches a lead in the consumer circuit that is carrying current but is not insulated, he is protected by this transformer (protective separating transformer).
Principle
When a separating transformer is used, there is no conductive connection between the primary circuit (“ring main”) and the secondary circuit (“consumer circuit”). There is no voltage between the consumer circuit and earth. When a person touches a lead in the consumer circuit that is carrying current but is not insulated, he is protected by this transformer (protective separating transformer).
Benefits
Tasks
How can a dangerous flow of current from an L-lead through the human body to earth be prevented?
Set up a power supply with a protective separating transformer.
