What is a Riser Pole Arrester ?

 

Bob Hileman

 A Riser Pole arrester is a type of arrester that is used to protect the insulation of cable and transformers on underground circuits.  How are they any different from a standard arrester?   Check out this new ArresterFacts and you can see.  You will also see an excellent full page labeled diagram of a riser pole that shows more than just the arrester.  Enjoy

ArresterHistory Early History of the Arrester Disconnector
 
  
The arrester disconnector is a silent setinal until the final moment in the arrester's life when it saves the power system from a long term outage.  This device has a rich patent filled history with a patent pile at least a foot thick.  This month's ArresterHistory document is about the early yearsof this important device.  The disconnector as we know it today was invented in 1939 by Ralph Earle (2,296,708).  It was the first time an explosive was used to separate the arrester ground terminal from the bottom of the arrester.  This concept is still used today in modern disconnectors.  The longevity of this arrester concept (70 years) is a testament to the quality of Earle's idea so many years ago.    Enjoy

Arrester Patent Review

This month we have a very simple and potentially very useful application.  The general concept is to install a port in the side of an arrester that is optically clear for inspection of the internal parts.

Surge Protection Hall of Fame

 Don Worden



Donald M Worden
Standards Champion, Designer, and Marketer of Low Voltage SPDs
 
Don Worden was a master at guiding standards development in the IEEE SPD.  His leadership is matched by very few.  When he retired from standards leadership 5 years ago, he left a legacy of published standards that may never be matched.  Besides Dons tireless leadership to publish useful standards, there are very few people that can use humor as well as he.  To this day, he can start and end each public speaking event with a line that will put you in the right mental state to listen and remember what he has said.  A very useful tool in communications.   
 
Don's career includes design and installation of industrial facility and broadcast station low voltage power distribution systems; aircraft ground power units; development of electromechanical devices and instrumentation for aircraft, missile, and industrial systems. In 1970 he discovered surge protection and along with that, a lifelong passion . The following 30 years focused on development, application and marketing of surge protection to resolve a wide spectrum of reliability needs and operational problems in low voltage power, communications, data, signaling and control circuits. Don says  "All of it was interesting; most of it was fun."
 
Words of Wisdom for future surge protection engineers
Find work that you enjoy and give it your full attention. Choose projects for which you have passion, even in difficult periods. Set realistic and measurable goals; evaluate your performance. Do not be afraid to innovate; progress frequently entails some risk. Learn from your accomplishments and your mistakes; never stop learning. Honesty, humor and hard work will contribute significantly to your success.
Work for the benefit of all parties - in the long run, you will gain more than you give in knowledge, personal satisfaction and friendships.
Note: Standards development and company projects have no room for those who participate solely to gain an advantage over their competition.
