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.". 517 $aANSI/IEEE Std C62.41-1980: IEEE Guide for Surge Voltages in Low-Voltage Ac Power Circuits 606 $aOvervoltage 606 $aElectric circuits$xAlternating current 606 $aElectric currents, Alternating 606 $aTransients (Electricity)$xStandards 615 0$aOvervoltage. 615 0$aElectric circuits$xAlternating current. 615 0$aElectric currents, Alternating. 615 0$aTransients (Electricity)$xStandards. 676 $a621.317 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279556303316 996 $aANSI$92072434 997 $aUNISA
