3. Protection against voltage and electromagnetic interference
Disturbances that may affect electrical installations are :
power-frequency surges ;
atmospheric power surges ;
electromagnetic interference.
3.1 Power-frequency surges
These overvoltages are caused by faults between HV and LV installations. The rules designed to limit their values depend on the characteristics of the HV installation and the transformer station's grounding diagram. They are defined in the standards dealing with HV installations (NF C 11-201, NF C 13-100 and NF C 13-200).
These rules define the value of the resistance of the earth connection of the HV/LV transformer substation so that the overvoltage...
