Call of the Month for December 2011
EPRI and TVA Invite Attendees and Exhibitors to 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.
C4.110 final report is now available
The CIGRE joint working group C4.110 final report is now available. Entitled "Voltage Dip Immunity of Equipment and Installations", the report is available at no cost for download on the Union of Electricy Applications (UIE) website at www.uie.org/node/401. EPRI worked closely with this joint working group over is effort over a three year period. The findings from this report should be instrumental in guiding future voltage sag related power quality standards.
PQView / PQWeb Users Group
The PQView® Users Group is intended to assist power quality engineers in managing and analyzing power quality data. The user group's purpose is to support and inform the PQView user and to provide a forum for communication and sharing of ideas among its members.

EPRI Calls on Industry to Build a Better AC Ice Cube Relay
Modern industry requires a more robust alternative to the standard AC ice cube relay. If SEMI F47-compliant units are made available, many power quality-related shutdowns could be avoided and industrial plants could save from several hundred thousands to several millions of dollars each year.
EPRI is calling on the manufacturers of control components to develop a line of control relays with improved voltage-sag robustness
