GB/T 18802.312-2017
ActiveComponents for low-voltage surge protective devices—Part 312: Selection and application principles for gas discharge tubes(GDT)
低压电涌保护器元件 第312部分: 气体放电管( GDT )的选择和使用导则
Application Summary AI generated
This standard provides guidelines for selecting and applying gas discharge tubes (GDTs) in low-voltage surge protective devices (SPDs). It is used by electrical engineers and designers to ensure proper GDT performance in power distribution and telecommunications systems, particularly for overvoltage protection in industrial, commercial, and residential installations. The standard covers criteria such as voltage ratings, impulse discharge currents, and coordination with other protective components to enhance system reliability.
