Transmission Earthing Devices
WHY ?• Secure the operators on the network • Secure the network equipments
WHEN ?
• Before working on a network which must be switching off • Immediately after performing the nominal voltage checking
HOW?
• Compliance with 5 golden rules • Creating a connection between the conductor and earth (s) conductors (s) phase in
respecting the order of installation / removal • Using earthing equipments that conforms to all relevant standards:
IEC / EN 61230: Temporary Mobile Grounding devices IEC / EN 61138: Lead copper cable for temporary mobile grounding devices EN 50508: Insulating sticks IEC / EN 60855-1 & CEI/EN61235: Insulating tube for live line working
• By following the minimum approach distance during installation of the line clamps
