Interruptions in Manufacturing...

...processes can cost as much as $2 million dollars in revenue per day. Such interruptions can be due to voltage sag events caused by ice storms, floods, hurricanes, lightning, utility power distribution equipment failures, or other system anomalies. EPRI has a variety of services and products to improve the robustness of your facility to power quality disturbances and help you understand, test, and comply with power quality standards such as the ITIC curve, IEC-61000-4-34, IEC-61000-4-11, and SEMI F47 "Specification For Semiconductor Process Equipment Voltage Sag Immunity."

Join Us for the 2011 PQ and Smart Distribution Conference and Exhibition

Join us this summer in Music City, USA, as we seek to bring harmony to the emerging Smart Grid. The Electric Power Research Institute (EPRI) and TVA—along with the Tennessee Valley Public Power Association and the local conference host, the Nashville Electric Service—invite you to the 2011 EPRI Power Quality (PQ) and Smart Distribution Conference and Exhibition. With the accelerating pace of the Smart Grid, there is a need to ensure that the future grid is robust, manageable, and effective from the transmission and distribution down to end-use loads. We encourage you to join us in Nashville to learn all the possibilities for your own applications.
