Electrical protection of persons
Protection against direct contact
- Measures of protection against direct contact
- Additional measure of protection against direct contact
Protection against indirect contact
- Measures of protection: two levels
- Automatic disconnection for TT system
- Automatic disconnection for TN systems
- Automatic disconnection on a second fault in an IT system
- Measures of protection against direct or indirect contact without automatic disconnection of supply
Protection of goods in case of insulation fault
Implementation of the TT system
Implementation of the TN system
- Preliminary conditions
