All rights reserved. viiIntroduction This introduction is not part of IEEE Std C62.42.0-2016, IEEE Guide for the Application of Surge-Protective Components in Surge-Protective Devices and Equipme
43、nt PortsOverview. External electrical events, such as lightning, can couple into a system by the mechanisms of direct coupling, electric fields, magnetic fields, and electromagnetic fields. Depending on the coupling mechanism, the coupling level can be reduced by the use of equipotential bonding, is
44、olation, and shielding. Once the surge is in the system it can be further mitigated by the use of surge-protective components in surge-protective devices and the equipment ports. The surge appearing in the system may be a voltage wave or a current wave or both. At a given location the surge may be c
45、ommon-mode or differential-mode or a combination of both. The choice of protection configuration and components will depend on the type of expected surge and the system parameters. Surge-protection component functions are either non-linear limiting or linear attenuating. Both types of protective fun
46、ctions can be used together to achieve the optimum surge mitigation. For example, an isolation transformer could be used to provide a galvanic break and common-mode voltage surge mitigation together with non-linear voltage limiters connected across the transformer windings to provide differential-mo
47、de voltage surge mitigation. Clause 3 of this document describes the different terms used in protection engineering. Clause 4 describes the mitigation function types. Clause 5 outlines available protection component technologies and characteristics. Clause 6 provides some examples of protection conf
48、igurations and their protection components. Component surge performance is evaluated by testing with a specified impulse generator. Informative Annex B, Annex C, and Annex D describe the various types of impulse generators, their interaction with surge-protective components, and the resultant compon
49、ent electrical stress levels. IEEE Std C62.42.0-2016 IEEE Guide for the Application of Surge-Protective Components in Surge-Protective Devices and Equipment PortsOverview Copyright 2017 IEEE.
