IEEE C62.50-2012 pdf free.IEEE Standard for Performance Criteria and Test Methods for Plug-in (Portable) Multiservice (Multiport) Surge- Protective Devices for Equipment Connected to a 120 V/240 V Single Phase Power Service and Metallic Conductive Communication Line(s).
The purpose of this project is to provide a unitirn specification/test document for design and application engineers, specifiers. and test laboratories to use in designing and testing this type of surge protective device.
1.3 Contents and context
This standard is divided into eight clauses. Clause I provides the scope and purpose of this standard. Clause 2 lists references to other standards that are useful in applying this standard. Clause 3 provides definitions that are either not found in other standards, or have been modified for use with this standard. Clause 4 specifies the device markings. Clause 5 describes in general terms the surge environment in which the protectors are expected to perform their protective function, and the rationales for the tests. Clause 6 provides specific test procedures for the power port functions. Clause 7 provides specific test procedures for the communications port functions. Clause 8 provides specific test procedures for the assessment of the protected-side inter-service and ground loop surge coupling performance.
This standard also contains two informative annexes. Annex A provides an overview related to the reasons will remain a declared value. Annex IL the bibliography, provides a list of citations.
2. Normative references
The following referenced documents are indispensable fur the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.
3. Definitions
For the purposes of this document, the following terms and definitions apply. The IEEE Siandards
Diclionari’ Online should be consulted for terms not defined in this clause.5
available interrupting capacity (AIC): The highest rms current at the rated nominal system voltage of the multiservice surge protective device (MSPD) that the MSPD disconnector is capable of interrupting under specified circuit power factor conditions.
disconnector (power SPI)): Device for disconnecting a surge protective device (SP[)), or part of an SPD. from the power system in the event of SPD failure. (adapted from (EC 61643-11:2010 Ed 1.0)
NOTE I —The disconnecting device is not required to have isolating capability for safety purposes. It is intended to prevent a persistent fault on the system and may give visible indication of the SPD failure.6
NOTE 2—Disconnectors can be internal (built in) or external (required by the manutácturer).
NOTE 3—There may be more than one disconnector function, for example an over-current protection function and a thermal protection function. These functions may be in separate units.
ground surge current reduction ratio: Quotient of the peak surge current in a service or reference ground by the peak surge current in a ground loop formed by equipment connection and interconnection. maximum continuous operating voltage (MCOV): The maximum designated root-mean-square (rms) value of the power frequency voltage that may be continuously applied to the mode of protection of a surge protective device (SPD).IEEE C62.50 pdf free download.
