Program 1 Research Portfolio
Electric utilities worldwide consistently report that power quality (PQ) is a fundamental component of the three key utility business performance metrics: system performance, economic performance, and customer satisfaction. By applying EPRI's extensive PQ expertise, the Power Quality research program may help to improve these three metrics, allowing PQ managers and transmission and distribution (T&D) asset utilization and system planning professionals to use PQ-related technology, knowledge, and expertise to help improve their organization's bottom-line performance.

Call of the Month for April 2012
Via EPRI’s PQ Knowledge (PQK) Power Quality Hotline, PQK funders asked PQ engineers at EPRI to discuss the accuracy of using line CTs and sensors to measure current at frequencies below and above the fundamental frequency (50/60 Hz).
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.
2012 EPRI Power Quality and Smart Distribution Conference and Exhibition
Join us this June 2012 in San Antonio, Texas -- the city known for its fighting spirit and the site of the great battle of the Alamo -- as we look to manage the increasing complexity of the evolving Smart Grid. The Electric Power Research Institute (EPRI) and CPS Energy invite you to the 2012 EPRI Power Quality (PQ) and Smart Distribution Conference and Exhibition. Also, utilities, industry representatives, and electric power end users are invited to participate by sharing their unique perspectives on the importance of addressing quality, reliability, and optimization of the power-delivery and end-use system.
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
Utility Interest Group: Flicker Issues for Industrial Customers
This project will provide information on flicker guidelines, indices, and assessments for industrial customers. It will also provide a forum for the development of consistent methods of applying the latest flicker standards and of evaluating compliance with the standards.
