GB/T 18802.31-2016 Translated English of Chinese Standard. (GBT 18802.31-2016, GB/T18802.31-2016, GBT18802.31-2016): Low-voltage surge protective devices - Surge protective devices for specific application including d.c. - Part 31: Requirements and tests for SPDs in photovoltaic applicationsThis part specifies the performance requirements and test methods for SPDs installed on the DC side of a photovoltaic system. This type of SPD is used to reduce the impact of lightning induction or direct lightning on the DC side of photovoltaic power generation equipment. These appliances will be connected to the DC power circuit of a photovoltaic power generation equipment which has a rated voltage not exceeding 1500 V. |
