Electrical Earthing System Design & Soil Resistivity Testing
The most exciting concept to come out of the Lightning Protection sector for centuries is the idea of ‘Lightning Strike Prevention’.
Now, preventing lightning itself is outside the scope of any working installation today. And maybe something for the scientific communities to think over. However, preventing an STRIKE-attachment to a structure IS something that is here and now! [Read more…] about Is prevention better than cure? | Lightning Strike Prevention
An example of a relatively recent innovation in protection concept introduced to the IEC standard IEC 62305. Is the Isolated LPS (Lightning Protection System). The Isolated LPS can be described as protection measures (e.g. lightning conductors) that achieve sufficient ‘separation‘ distance, electrically and/or physically, between that which is conducting the Lightning Current. That which is to be protected from the effects of the lightning current. This separation distance is what gives this methodology its label i.e. ‘Isolated’ design. It does NOT mean the system is electrically isolated from earth (a common misconception). It just refers to the physical distance achieved between the lightning current and the item being protected.
