Pac World is the best magazine I have read covering the subjects of protection, automation and control. It is not often I read magazines cover to cover.

PAC World: Dear Ian,

PAC World: Thank you, Luis for the information. It will be nice if you or someone else will volunteer to prepare a summary of the report that we can publish in the September 2010 issue of the magazine. If anyone is interested, please send an e-mail to editor@pacw.org.

My name is Ian Riensche, member of the Western Protective Relay Conference Committee, and protection engineer at Tacoma Power in Tacoma, Washington, USA. 
I am also the Sudoku editor for two newspapers.  I would like to submit a very challenging Sudoku puzzle for possible inclusion in the
next issue of PAC World magazine.  This puzzle is my creation and rates very high on the difficulty scale; as such, I think it would be an enjoyable challenge to your readers.
Ian Riensche, P.E.

PAC World: Thank you, Ian. We all know that our colleagues from the PAC industry live for challenges. So let us see who will be the first to send the solution to editor@pacw.org.
