This site is provided for the benefit of funders of the EPRI Power Quality Knowledge program (PS1D). For those seeking to learn more about EPRI PQ Knowledge, please contact me, Bill Howe, Program Manager of Power Quality research for EPRI.
To take advantage of the PQ Online Resource Center, please register for MyPQ. “Guest Level” access privileges will be granted initially to all registrants. “Funder Level” access will be granted automatically to funders through manual review of new “MyPQ” registrants — a process that may require 1-2 working days. Please contact Bill Howe if you are an EPRI PQ Knowledge (PS1D) funder and your need for “Funder Level” access is urgent.
Again, Welcome to the PQ Online Resource Center!
Call of the Month for January 2010
Via EPRI's PQ Knowledge (PQK) Power Quality Hotline, a PQK funder asked EPRI engineers how interharmonics can cause voltage variation. The funder read though the PQ Encyclopedia on "Understanding Voltage Flicker" but wanted to know more about intermodulation between the 60-hertz power frequency and the frequency of a an interharmonic.
EPRI PQ and Smart Distribution 2010 Conference and Exhibition
"Transporting You into the 21st Century Distribution System"
June 14 - June 17, 2010
Location: Fairmont Le Château Frontenac, Québec City, Canada
Come join us this summer in the heart of historic Old Québec - one of Europe's oldest American settlements - as we explore new paths in the drive toward the emerging Smart Grid. EPRI and Hydro-Québec invite you to the 2010 EPRI Power Quality (PQ) and Smart Distribution 2010 Conference and Exhibition as we explore the future challenges of power quality, smart distribution, and electric transportation. The rapid growth of power quality data coupled with smart distribution systems gives us the opportunity to explore new possibilities to manage and improve the grid efficiency. We encourage you to attend and discover all the possibilities for your own application.
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
