本标准适用于低压气体放电管（GDT）浪涌保护组件，用于电压小于或等于1000 V rms或1500 V dc的系统。这些保护组件设计用于限制平衡或不平衡通信电路以及从直流到420 Hz工作的电源电路上的电压浪涌。本标准包含一系列标准试验标准，用于确定气体放电管浪涌保护组件的电气特性和额定值。 本标准中的试验旨在作为IEEE标准在线词典中定义的设计试验，并提供各种气体放电管浪涌的比较方法- 保护组件。 气体放电管用于在电路中提供过压保护。当超过气体放电管的击穿（火花）电压时，管的正常高阻抗状态变为低阻抗状态，以允许气体放电管传导浪涌放电电流。在管传导浪涌放电电流后，它会中断功率跟随电流的流动，并返回其高阻抗状态。 本标准的试验标准和定义提供了一种通用的工程语言，有利于气体放电管浪涌的用户和制造商- 保护组件。 由于本文中包含的大多数测试中使用的电压和能量水平，所有测量都应被视为危险的，在进行测量时应适当小心。

This standard applies to low voltage gas discharge tube (GDT ) surge-protective components for application on systems with voltages less than or equal to 1000 V rms or 1500 V dc. These protective components are designed to limit voltage surges on balanced or unbalanced communication circuits and on power circuits operating from dc to 420 Hz. This standard contains a series of standard test criteria for determining the electrical characteristics and ratings of gas discharge tube surge-protective components. The tests in this standard are intended as design tests as defined in the IEEE Standards Dictionary Online and provide a means of comparison among various gas discharge tube surge-protective components. Gas discharge tubes are used to provide over-voltage protection in electrical circuits. When the breakdown (sparkover) voltage of the gas discharge tube is exceeded, the normal high-impedance state of the tube changes to a low-impedance state to allow the gas discharge tube to conduct the surge discharge current. After the tube conducts the surge discharge current, it interrupts the flow of power follow current and returns to its high impedance state. This standard's test criteria and definitions provide a common engineering language that is beneficial to the user and manufacturer of gas discharge tube surge-protective components. Due to the voltage and energy levels employed in the majority of tests contained herein, all measurements should be considered hazardous and appropriate caution should be taken in their performance.
