Lightning 1 - The effects of lightning Lightning directly or indirectly generates the following effects: thermal (blow-outs, fire) electrodynamic (loosening of terminals) rise in earth voltage (risk of electrocution) overvoltages of several thousand volts and destructive induced currents (damage to electrical and electronic equipment, interruption of operation) Choice of the level of lightning protection Prior to the installation of the lightning protection devices, the risk must be assessed, using a number of criteria: level of exposure of the area (,, ) location of the building power supply, neutral system TT, T, IT - underground - overhead the presence of a lightning conductor on/close to the building the type of equipment to be protected the cost of the consequences of the equipment not being available The level of this lightning protection is indicated as: medium ( ) high ( ) very high ( ) The protection must be chosen according to the most exacting criterion E.g. whatever the level of exposure, the presence of a lightning conductor requires a very high level of protection Additional protection will be necessary according to the sensitivity of the equipment to be protected (computing, electronic) and the area of the installation 1 - Defining the required level of protection (,, ) Location of the installation Level of exposure 2 - Protection against the effects of lightning This is based essentially on: catching and discharging the current to earth the use of the passive protection of the installation Passive protection (poor, good) designates the part of the protection provided by the structure and the configuration of the installation itself (neutral earthing system, area, level of equipotentiality, etc.) Regulation Standard E 61-643-11, characterises the indirect effects of lightning based on a 8/20 µs waveform, type 2 voltage surge protector and the direct effect by a 10/350 µs wave form type 1 voltage surge protector (v.s.p.) 100% 90% I Peak Building location tighly packed buildings scattered buildings isolated in mountains, close to a stretch of water or on top of a hill Power supply overhead underground Presence or proximity of a lightning conductor 2 - Determining the level of sensitivity of the equipment Level of sensitivity Equipment Protection level Low sensitivity motors, heating equipment > 2 kv Sensitive domestic electrical appliances, lights 1.5 to 2 kv High sensitivity computer equipment 1.5 kv 50% 10% 8 s t (s) The choice is specific to each installation and depends on: the required level of lightning protection (,, ) the sensitivity of the equipment the configuration of the installation (passive protection) 20 s When a voltage surge protector is installed on the power circuit, it is recommended that one is installed on the communication circuit (telephone line) More than 1 v.s.p. should be installed in electrical board and as closed as possible to the equipment to be protected The Lexic range is completed by proximity v.s.p.
