Electric power system compatibility with industrial process equipment. I. Voltage sags

Abstract

The purpose of this paper is to provide information that can be used to evaluate the compatibility between the electric power supply system voltage sags and electronic control devices integrated into industrial processes. Example sag data and equipment sensitivities are presented and it is shown how to combine the data to determine the economic loss due to voltage sags. Tradeoffs and alternatives in the power system, equipment design, and process design are discussed to minimize the impact of sag induced disruptions.<>
