IEEE C62.41.2-2002

The scope of this recommended practice is to characterize the surge environment at locations on ac power circuits described in C62.41.1 by means of standardized waveforms and other stress parameters.

The project has several purposes, technical coordination with its two companions, C62.41.1 and C62.45. It consists of a restructuring of C62.41-1991 (reaff '96) with an update of the data base. The recommended practice (dot 2 of C62.41) will apply the data base contained in C64.41.1 to recommend a limited set of test waveforms and other stress parameters to enable equipment designers to make technically sound and economic decisions concerning surge-protective devices. The two companion projects, C62.41.1 (PAR is being submitted simultaneously) and C62.45, will be developed in parallel so that the three documents will be published in synchronism rather than the staggered schedule occurring in the past for C62.41 and C62.45.

New IEEE Standard - Inactive-Reserved. This IEEE standards product is part C62 Family on Surge Protection and supersedes C62.41 The scope of this recommended practice is to characterize the surge environment at locations on ac power circuits described in IEEE Std C62.41.1-2002 by means of standardized waveforms and other stress parameters. The surges considered in this recommended practice do not exceed one half-cycle of the normal mains waveform (fundamental frequency) in duration. They can be periodic or random events and can appear in any combination of line, neutral, or grounding conductors. They include surges with amplitudes, durations, or rates of change sufficient to cause equipment damage or operational upset. While surge protective devices (SPDs) acting primarily on the amplitude of the voltage or current are often applied to divert the damaging surges, the upsetting surges might require other remedies.
