Transmission Line Arresters

ArresterWorks to develop guide for the condition assessment of lightning arresters installed on transmission lines for CEATI International (www.ceati.com )

Arresters have been protecting power lines in substation and on distribution lines for more than a century. Despite this long history, it has only been in the last 20 years that arresters have begun to be used on sub-transmission and transmission lines. This relatively new application of the arrester has left many users questioning how to verify the health of the arresters they have in service. At present, there are no comprehensive guides for the maintenance of arresters on transmission lines; however, this problem will soon be resolved.

CEATI International has retained ArresterWorks to write a transmission line arrester guide that will cover both the electrical and the mechanical maintenance aspects. The primary objective of this project will be to produce a guide that clearly shows how to use existing arrester condition assessment tools on transmission line arresters. The guide will assist CEATI Transmission Line Asset Management group members in understanding the health and the expected remaining life of their arresters, with focus on assessment methods currently available for both Non-Gapped Line Arresters (NGLA) and Externally Gapped Line Arresters (EGLA).

ArresterWorks First Patent

ArresterWorks granted its first arrester patent.
On April 29, 2014 ArresterWorks was granted US Patent No. 8,711,538 for an EGLA failure indicator. This device now makes the EGLA a more desirable arrester for line protection in that not only does it restore the original system BIL if the arrester should fail, but it also provides a visual indication that the arrester has failed.



April 2014

IEEE 2014 Conference

The 2014 IEEE PES T&D Conference & Exposition brought hundreds of manufactures and users together in Chicago. On display were a number of arresters in various applications. Click here to view photos from the exposition.

Besides the exposition there was a variety of technical papers presented. The Lightning Performance of Overhead Lines panel session was comprised of four informative presentations. Among them was a presentation by ArresterWorks', Jonathan Woodworth on Externally Gapped Line Arresters - A Critical Design Review




March 2014

Doble 2014 Conference

ArresterWorks' Jonathan Woodworth presented an update on engineering/economic study on lowering losses of transmission lines with arresters at the Doble International Conference in Boston, Massachusetts.

Power systems experience losses in many forms and a great deal of effort is put forth to reduce these losses in many areas. However the losses related to overhead ground wires (OHGW) of transmission lines arerarely mitigated on systems below 345kV. The losses relating to OHGWs are due to inductive currents from the phase conductors onto the OHGW or sometimes called shield wires. The study showed how arresters can be used in place of OHGWs on transmission lines to 100% eliminate induced losses and at the same time increase the reliability of the system.

The study was funded in part by NYSERDA and was conducted in cooperation with ArresterWorks, Ceralink Inc, Rensselaer University and Cornell University.




September 2013

Vancouver Harbor View

Vancouver's sunny days were the perfect backdrop for
INMR's 2013 World Congress
People involved in surge protection, from around the world, came to Vancouver to attended the congress.

Jonathan Woodworth

ArresterWorks' Jonathan Woodworth, session chair and co-organizer of the Congress Arrester Session, presented an engineering/economic study on lowering losses of transmission lines with arresters. The study, which is being funded in part by NYSERDA, is still in process and is being conducted in cooperation with ArresterWorks, Ceralink Inc, Rensselaer University and Cornell University.
More information on the project will be available in the future as it advances.

Pellet Arrester After years of procrastination, I have finally posted the beginings of our Arrester Museum (Virtual Style). The first exhibit is from a 1925-30 vintage Pellet Type arrester from GE. This is only the first of many exhibit postings. We hope to make this a collaborative effort of those that have photos of old arresters and are willing to share them. ArresterWorks will also gladly take donations of old arresters for our Museum and for the display in the virtual museum. Enjoy.....
