Scope: This guide documents methods and designs to mitigate interruptions and equipment damage caused by birds in different ways, such as electrocution, collision, contamination, and streamer outages in substations, transmission lines and distribution lines and their various components, such as insulators, bushings, capacitor banks, thereby improving reliability and minimizing the associated revenue loss including penalties due to the violation of wild life treaties as well as negative publicity.

Action: IEEE Guide 1651 has been submitted for publication.

Task Force: Insulator Contamination Testing and Dielectric Aging Performance (TF

Chair: Dr. Anibal de la O Lavalle, TYCO Electronics, 919-557-8855, 8000 Purfoy Road, Fuquay Varina, NC 27526

Scope: .

Next meeting: To be determined.

Task Force: Guidelines for Establishing Procedures for Live Line Working of Non Ceramic Insulators (TF

Chair: Tony Carreira, K-Line Insulators Ltd., 416-292-2008, 50 Passmore Ave., Toronto, ON, M1V 4T1, Canada

Scope: In co-operation with ESMOL, the Task Force will develop a common vocabulary and inspection criteria for the various changes in dielectric materials of transmission, distribution and substation insulators that occur with time and exposure. Electronic presentation of the results on an appropriate web site is a target deliverable.

Next meeting: February 16, 2011, 11-12 AM Las Vegas NV - Vdara Hotel, Room: Rafael 2.

Preliminary Guidelines

Task Force: Corona Testing of Hardware & Insulators   (TF

Chair: Dr. John Kuffel, Kinectrics, 416-207-6047, 800 Kipling Avenue, Toronto, ON, M8Z 6C4, Canada

Scope: A joint task force with TP&C Committee.

Task Force: Icing Test Methods & Mitigation Techniques (TF

Chair: Masoud Farzaneh, University of Quebec, 418-545-5044, 555 Boulevard de l'Universite, Chicoutimi, Quebec, Canada, G7H 2B1

Scope: Prepare guidelines for icing test methods and procedures to evaluate the electrical performance of insulators. Previous Task Forces have been refining test methods for freezing conditions, including ice and snow, since 1999.  The present Task Force will consolidate the findings and will  recommend specific, appropriate and reproducible test methods for selecting adequate insulators.  The scope includes test methods for substation and line insulators at distribution and transmission voltage levels.   The test methods detail special measures to reproduce the environmental and insulator parameters that influence the risk of flashover in freezing conditions. Statistical methods will also be recommended to assist in the insulator selection process.This will be achieved through deriving relevant test parameters from IEEE Std. 4 and other relevant standards and guides recommended by organisms such as CIGRE and IEC. Some of the work is being done jointly with DEIS and PES.

Action: This task force has published 5 papers during its work period. P1783 has been accepted as a new IEEE Standard (June 2009).

Chair: T. Grisham, GRISCUT Ltd. 630-584-1992, 935 South Third Street, St. Charles, IL 60174

Scope: Provide the first in a series of tutorials that focus on the design, installation and performance characteristics for distribution and transmission class insulators.  The content is directed at the younger engineer that has little knowledge of insulators, while providing a highly effective reference for experienced designers.  Specifically, this group will develop a tutorial that focuses on the history, types of designs, processes of manufacturing, in-process inspection, qualification by ANSI standards, performance characteristics and field installation requirements.  Ultimately, this work will result in the publication of an IEEE guide.
