Devices manufactured by ELGAS are designed to have very high immunity to interference. They are tested according to valid standards (set of standards ČSN EN 61000 4) for radiation (EMI) and resistance (EMC) to electromagnetic interference in an industrial environment (see [29], [30], [31]).
Page 61 5 Installation and Commissioning The first level is protection against the effects of lightning. The protection is realized by overvoltage protection SPD type 1, which is placed in the low-voltage part of the substation or in the main switchboard of the building. It serves mainly to limit atmospheric overvoltage. The second level of protection is usually realized by overvoltage protection SPD type 2, which is usually located in the secondary switchboard and further reduces the magnitude of the overvoltage value for the next third stage.
