10、00 V (dc) Circuits. This guide is a revision of IEEE Std C62.42-1992 and has been rewritten to include metal oxide varistor (MOV) and avalanche junction semiconductor component surge-protective devices in addition to gas tube and air gap arresters, which were the subjects of the previous document. T
11、his guide supplements IEEE Std C62.31-1987a,b, IEEE Std C62.32-1981, IEEE Std C62.33-1982, and IEEE Std C62.35-1987. The purpose of this guide is to assist in selecting the most appropriate type of device for a particular application, and in evaluating the characteristics of devices to meet specific
12、 service requirements. IEEE Std C62.42-2005 includes an explanation of the electrical environment in which component surge-protective devices shall operate, a comparison of the major difference among the four types of devices considered. It also includes a description and the theory of operation of
13、gas tube, air gap, MOV and avalanche junction semiconductor devices, as well as guidance in applying and interpreting the respective test specifications for the arrester characteristics.

The following are examples o
33、f those who can benefit from this guide: One who designs low-voltage surge protectors and desires an overview of the application of component surge-protective devices, or combination of component surge-protective devices used within surge protectors. One who designs low-voltage power, data, communic
34、ations, or signaling products or systems and desires guidance on selecting appropriate component surge-protective devices to be used directly within the product or system as part of the initial product/system design (i.e., protection designed as an integral part of the product or system). One who ne
35、eds to solve a surge protection problem in the field and seeks guidance on selecting and installing appropriate component surge-protective devices to solve the problem (e.g., consultants or field service personnel who need to provide ad hoc surge protection for a product or system in order to resolv
36、e a problem). One who desires to ensure appropriate surge protection of a system in the early stages of design and needs to gain an overall appreciation of the technology. This guide is divided into nine clauses. Clause 1 provides an overview and scope for this guide. Clause 2 lists references. Clau
37、se 3 lists definitions. Clause 4 describes the electrical environment. Clause 5 compares some of the major characteristics of component surge-protective devices. Clause 6, Clause 7, Clause 8, and Clause 9 give a description and theory of operation and guidance in applying and interpreting the respec
38、tive test specifications for component gas tube (Clause 6), air gap (Clause 7), metal-oxide varistor (Clause 8), and avalanche junction semiconductor (Clause 9) surge-protective devices. This guide also contains five informative annexes, which provide examples of applications of component surge-prot
39、ective devices in surge protectors, equipment, and/or systems, and a bibliography.
