Product Description

EPP series AC power lightning protector consists of multiple single lightning protection chips, which can be freely combined into single-phase or three-phase protection for different power distribution systems to prevent damage to low-voltage power equipment from inductive overvoltage or operational overvoltage.EPP65T is usually used for secondary protection.
 

Protection in stages Editorial Podcast
The first level lightning protector can be for direct lightning current discharge, or when the power transmission line suffered a direct lightning strike conducted by the huge energy discharge, for the possibility of direct lightning strikes, must be carried out CLASS-I lightning protection. The second level lightning arrester is for the residual voltage of the former lightning arrester and the induction of lightning strikes in the area of protection equipment, for the former level when a large lightning strike energy absorption, there is still a part of the equipment or the third level lightning arrester is quite huge energy will be transmitted, the need for the second level lightning arrester to further absorb. At the same time, after the first level of lightning protector transmission line will also induct lightning electromagnetic pulse radiation LEMP, when the line is long enough to induce lightning energy becomes large enough to require the second level lightning protector to further implement the lightning strike energy discharge. The third level protector protects the LEMP and the residual lightning energy that passes through the second level protector [1].

Protection in stages
The first level of protection
The purpose is to prevent the surge voltage directly from the LPZ0 zone conducted into the LPZ1 zone, tens of thousands to hundreds of thousands of volts of surge voltage limit to 2500-3000V.
Into the power transformer low-voltage side of the installation of power lightning protector as the first level of protection should be three-phase voltage switch type power lightning protector, the lightning flux should not be less than 60KA. the level of power lightning protector should be connected to the user power supply system inlet between each phase and the earth's high-capacity power lightning protector. Generally require the level of power lightning protector with a maximum impact capacity of 100KA or more per phase, the required limit voltage is less than 1500V, called CLASS I power lightning protector. These electromagnetic lightning protectors are designed to withstand high currents from lightning and induced lightning strikes and to attract high-energy surges that can divert large amounts of surge current to earth. They only provide limiting voltage (inrush current flow through the power supply lightning protector, the maximum voltage appearing on the line is called limiting voltage) for the medium level of protection, because CLASS I protectors are mainly absorbed by large surge currents, they alone can not fully protect the power supply system inside the sensitive power equipment.
The first level of power supply lightning protector can prevent 10/350μs, 100KA lightning wave, to the highest protection standards specified by IEC. Its technical reference is: lightning flux greater than or equal to 100KA (10/350μs); residual voltage value is not greater than 2.5KV; response time is less than or equal to 100ns.
