• Math Bollen, Co-chair
• Russ Ehrlich, Secretary
• Previous meeting minutes approved
• Paper Session to be held this afternoon: Papers to be posted on the web site
• IAS meeting minutes should be included on Web site
• Need to get IAS meeting minutes

• Definitions from 1250 & 1433 as applicable will be used or referenced
• Dennis Hansen, Will look at the definitions pertinent to this topic.
• We will use IEEE definitions to start
• We need a definition of what the Sag Index is used for?
• Methodologies
• Math Bollen - Chalmers University of Technology
• Provided discussion on methodology and how to incorporate existing work
• Discussions:
• Different methodologies for transmission system
• Necessity of system statistics for comparision
• Scalable system requirements
• The need for a standard on how to data
• Performance based rates will need data, how is that data gathered?
• Concerns:
• System construction, weather, location need to be looked at
• 1366 stopped at this level
• Gold book, Chapter 9, theoretical
• No Method exists for sags
• Number of monitors required for effective data
• Need for secion in the guide for these topics

• Math will discuss/develop methodologies & criteria
• Dan Sabin, Work from Electrotek has already been performed.
• DPQ Project worked through monitor location selection, possible incorportation
• The Outline:
• System - Statistics
• Site - Statistics
• Magnitude & Duration
• Magnitude & Time
• Voltage Samples

• Individual feeder level
• Substation level
• Minimum levels
• Use of current values to calculate & identify other information (This is a modeling tool, not index, not to be incorporated into this guide)

• Dan Sabin will forward papers to be posted on Web site
• Math will arrange paper into his terminology, paper will be posted on Web site. Paper to identify existing IEEE work products ie. 1250, 1433, 1159.2, etc
• Dennis will look at definitions and provide information
• Russ will provide format, The format of the meeting minutes should follow the outline of the final product: Definitions; methodology; measurements; etc.
• E. Gunther, will provide CIGRE/CIRED paper to be posted on Web site
• IAS meeting is in Rome
• P1564 will not meet in Rome, but P1564 will meet at the WPM in Columbus, OH.
