IEEE C62.64:2009 pdf download.IEEE Standard Specifications for Surge Protectors Used in Low-Voltage Data, Communications, and Signaling Circuits.
IEEE C62.64 applies to surge protectors for application on multi-conductor and coaxial, balanced or unbalanced, data, communications, and signaling circuits with voltages less than or equal to I 000 V rms, or 1200 V dc. These surge protectors are intended to limit voltage surges. current surges, or both.
This standard is not intended to cover individual device components. Installation of all surge protectors (SPDs) must be in conformance with the requirements of applicable local and national electrical codes.
Specifically excluded from this standard are protectors for low-voltage power circuit applications.
The surge protectors covered by this standard are to be tested by means of the connections or terminations that arc used when the surge protector is installed in the field. For surge protectors that are intended to be used with a base or connector, that base or connector shall be part of the tests.
The tables of typical performance values of this standard 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.
1.2 SPD configurations
The surge protectors covered arc multiple-component series or parallel combinations of linear or nonlinear elements, packaged for the purpose of limiting voltage, current, or both. Figure 1 is based on Figure 1 of IEEE Std C62.36TM2OOO and illustrates functional block diagrams for the surgc protectors covered by this standard.
1.3 Use of this standard
1.3.1 Application types
Tables of applications in this standard often refer to application types. In such tables, each application type is given an alphanumeric designation that refers to a typical value(s) for that specific application. All of the typical values on the same row as the designator apply to that application type.
A given surge protector has the same designation in all application type tables. For exampic, a surge protector has application type designation A for the insulation resistance specification, and also application type designation A for thc other specifications such as impulse-limiting voltage and impulsc reset.
Table 12 describes the application types includcd in this document. For each application type (e.g., A), a short description is provided on the main characteristics of the surge protector (e.g., where used). Furthermore, each application type has further subcategories that address different designs of surge protectors applied to the same application type.IEEE C62.64 pdf download.
