IEEE C62.62 This standard applies to surge-protective devices intended to be installed on the load side of the main servicedisconnect packaged to be connected to 50 Hz or 60 Hz ac power circuits rated at 1000 V(rms) or less. Performance characteristics and standard methods for testing and rating are established for these devices, whichmay be composed of any combination of components. The tests in this standard are aimed at providingcomparisons among the variety of surge-protective devices available.
Many of the tests described in this standard may stress a surge-protective device.Care should be taken toensure that stressed devices are not compared with unstressed devices unless that is the desired intent. Thesuppression characteristics of some surge-protective devices change with successive surging as well as withchanges in the environment. These changes may be permanent in nature. Selection and careful organizationof appropriate tests can reduce the quantity of test samples needed.
The voltage and energy levels employed in the majority of the tests described in this standard are hazardousand appropriate cautions must be exercised in their performance.
The purpose of this standard is to provide users, independent laboratories, and manufacturers with test meth-ods and test specifications applicable to low-voltage surge-protective devices, intended for limiting transientovervoltages that can appear on ac power circuits of 1000 V (rms) or less.
This standard shall be used in conjunction with the following publications. When the following standards aresuperseded by an approved revision, the revision shall apply.
combination wave: A surge delivered by an instrument that has the inherent capability of applying a1.2/50-voltage wave across an opencircuit, and delivering an 8/20-current wave into a short circuit. Theinstantaneous impedance to which the combination wave is applied determines the exact wave that is deliv-ered. The peak magnitudes of the voltage or current wave shall be specified.Syn: combination surge.IEEE C62.62 pdf download.
