Abstract In order to effectively suppress lightning electromagnetic pulse, the selection of protection devices(also called Surge Protection Device)are essential.The surge protective device has many varieties in the market and each has its specific features with wide distribution in technical parameters.So it brings a lot of problems to the workers of lightning protection when they select the surge protection device.This paper analyzes the selection principles of surge protector with low-voltage distribution system and its requirements for the main technical parameters.As the example of Phoenix lightning protection module, based on the selection principles and technical parameter requirements, the installation location, installation series, technical specifications and classification test levels of surge protector in the building are given out so as to provide some useful theoretical basis for the lightning protection workers in the correct selection of surge protector with low-voltage distribution system.
