Low Voltage Power SPDs

Institute of Electrical and Electronics Engineers, Inc. (IEEE) and American National Standards Institute (ANSI) standards, guides, and recommended practices regarding low voltage power surge protective devices.

IEEE Std C62.34 TM -1996 (R2001) Standard for Performance of Low-voltage surge-protective devices (Secondary power surge arresters)

Reaffirmed 2001 surge arresters designed for application on the low-voltage ac supply mains (1000 V rms and less, frequency between 48 Hz and 62 Hz) are covered.

IEEE Std C62.62 TM -2000 IEEE Standard Test Specifications for surge protection for Low-Voltage AC Power Circuit

This standard establishes methods for testing and measuring the performance characteristics for surge-protective devices used in low-voltage ac power circuits. Definitions are stated that apply specifically to surge-protective devices. The testing requirements are categorized into two groups, in which a minimum set of basic tests (BTs) are prescribed for all surge-protective devices within the scope of its documents, supplemented by additional tests (ATs) that might be needed to establish particular application requirements.

IEEE Std C62.41.1 TM -2002 Guide on the Surge Environment in Low-Voltage (1000 V and Less) AC Power Circuit

This is a guide describing the
surge voltage, surge current, and temporary overvoltages (TOV) environment in low-voltage [up to 1000 V root mean square (rms)] ac power circuits. This scope does not include other power disturbances, such as notches, sags, and noise.

IEEE Std C62.48 TM -1995 IEEE Guide on Interactions Between Power System Disturbances and surge protection device.

Information is provided to users and manufacturers of surge protectors(SPDs) about the interactions that can occur between SPDs and power system disturbances. This guide applies to SPDs manufactured to be connected to 50 or 60 Hz ac power circuits rated at 100–1000 V RMS. The effects of the presence and operation of SPDs on the quality of power available to the connected loads are described. The interaction between multiple SPDs on the same circuit is also described.

IEEE Std C62.41 TM -1991 (R1995) IEEE Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuit

C62.41 is superseded by C62.41.1-2002 and C62.41.2-2002 A practical basis is provided for the selection of voltage and current tests to be applied in evaluating the surge withstand capability of equipment connected to utility power circuits, primarily in residential, commercial, and light industrial applications. The recommended practice covers the origin of surge voltages, rate of occurrence and voltage levels in unprotected circuits, waveshapes of representative surge voltages, energy and source and impedance. Three locations categories are defined according to their relative position from the building service entrance. For each category, representative waveforms of surge voltages and surge currents are described, organized in two recommended "standard waveforms" and three suggested "additional waveforms."

IEEE Std C62.41.2 TM -2002 Recommended Practice on Characterization of Surges in Low-Voltage (1000 V and Less) AC Power Circuit.

This IEEE standards product is part C62 Family on surge protection and supersedes C62.41 Abstract: 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.

IEEE Std C62.45 TM -2002 IEEE Recommended Practice on Surge Testing for Equipment Connected to Low-Voltage (1000 V and Less) AC Power Circuits

This IEEE standards product is part C62 Family on lignting surge protection. Abstract: The scope of this recommended practice is the performance of surge testing on electrical and electronic equipment connected to low-voltage ac power circuits, specifically using the recommended test waveforms defined in IEEE Std C62.41.2 -2002. Nevertheless, these recommendations are applicable to any surge testing, regardless of the specific surges that may be applied.

IEEE Std C62.72TM-2007 IEEE Guide for the Application of surge protection device for Low-Voltage (1000 V or Less) AC Power Circuits

Information is provided to specifiers and users of surge arresters (surge protectors, SPDs) about the application considerations of ac power surge arresters associated with power distribution systems within North America. This guide applies to surge protection devices to be connected to the load side of the service entrance main over current protective device of 50 Hz or 60 Hz ac power circuits rated at 100 V to 1000 V rms. The effects and side effects on the presence and operation of surge protectors in low-voltage power distribution systems are described. The coordination of multiple SPDs on the same circuit is described.
