Standard Details
Covered in this guide is the application of surge protective devices (SPD) and surge protective circuits (collectively called surge protectors) used to protect information and communication technology (ICT) circuits, including smart grid. This guide is not intended to cover individual surge protective components. Specifically excluded from this guide are stand-alone ac power protectors.

This Amendment covers changes made to C62.43.1 in response to post-publication comments.

Existing Standards |
Superseded by C62.36-1994. Methods for testing and measuring the characteristics of surge protectors used in low voltage data, communications, and signaling circuits with voltages less than or equal to 1000 V rms or 1200 V dc are established. The surge protectors are designed to limit voltage surges, current surges, or both. The surge protectors covered are multiple-component series or parallel combinations of linear or nonlinear elements. Tests are included for characterizing standby performance, surge-limiting capabilities, and surge lifetime. Packaged single gas-tube, air-gap, varistor, or avalanche junction surge-protective devices are not covered, nor are test methods for low-voltage power circuit applications.

Superseded by IEEE Std C62.43-2005. Assistance is provided for the selection of the most appropriate type of low-voltage data, communications, and/or signalling circuit surge protector for a particular application or set of conditions. Surge protector functions and characteristics are also explained and evaluated. AC power circuit applications are not addressed in this document.

This standard applies to surge protectors for application on multiconductor and coaxial, balanced or unbalanced, data, communications, and signaling circuits with voltages less than or equal to 1000 V rms, or 1200 V dc. These surge protectors are intended to limit voltage surges, current surges, or both.

Reaffirmed December 2010. This guide provides assistance in selecting the most appropriate type of surge protector for a particular data, communication, and/or signaling circuit application. The purpose of this guide is to enable an understanding and an evaluation of the functions of the various types of multiple-component data, communications, and signaling circuit protectors in terms of particular applications.
|
|
Surge protectors for application on multiconductor and coaxial, balanced or unbalanced, data, communications, and signaling circuits with voltages less than or equal to 1000 V rms or 1200 V dc are covered. These surge protectors are multiple-component series or parallel combinations of one or more nonlinear elements and zero or more linear elements. The tables of typical performance values provide a means of comparison among various surge
protectors. They also provide a common engineering language beneficial to the user and manufacturer of surge protectors used in low-voltage data, communications, and signaling circuits.

Surge protectors for application on multiconductor balanced or unbalanced data, communications, and signaling circuits with voltages equal to or less than 1000 Vrms, or 1200 V dc are covered by this standard. These surge protectors are designed to limit voltage surges, current surges, or both. The methods of testing and criteria for determining the end of life of electrical surge protectors used in low-voltage data, communications, and signaling circuits are described. The surge protectors covered are multiple-component series or parallel combinations of linear or nonlinear elements, packaged for the purpose of limiting voltage, current, or both. This standard is not intended to cover packaged single gas tube, air gap, varistor, or avalanche junction surge-protective devices, which are covered by IEEE Std C62.31(TM), IEEE Std C62.32(TM), IEEE Std C62.33(TM), and IEEE Std C62.35(TM), respectively.

Surge protectors for application on multiconductor balanced or unbalanced information and communications technology (ICT) circuits and smart grid data circuits are addressed in this standard. These surge protectors are designed to limit voltage surges, current surges, or both. The surge protectors covered are generally multiple-component series or parallel combinations of linear or nonlinear elements, packaged or organized for the purpose of limiting voltage, current, or both. The methods of testing and criteria (where appropriate) for the characteristics and ratings of surge protectors used in ICT circuits and smart grid data circuits are also described in this standard. Packaged single gas tube, air gap, varistor, or avalanche junction surge-protective components are not covered by this standard, but rather are covered by IEEE Std C62.31?, IEEE Std C62.32?, IEEE Std C62.33?, and IEEE Std C62.35?, respectively. Specifically excluded from this standard are test methods for low-voltage power circuit applications. For protection of wire-line communication facilities under the specialized conditions found at power stations, consult IEEE Std 487?.
