A couple of questions on lightning protection as per IEC / EN  62305:2006 :
-

   Where to download the risk calculator program shown in IEC 62305-2?
   Has anyone experience of using the reinforced concrete foundations of
   extended structures ( e.g. overhead railway line ) for surge protection
   earth? The traction supply is 650V DC
