DESCRIPTION:[]\n\nTwo related electric safety topics will be covered in the
  presentation. (1) A ground grid is required for substations to carry and 
 dissipate current into earth under normal and faulty conditions for safety
  purposes. In the Ground Grid Design presentation\, the common concepts\, 
 basic requirements\, calculation methods\, and procedure of ground grid de
 sign will be discussed. (2) Electric Shock is the main safety issue for lo
 w voltage systems. In this presentation\, the concepts of low-voltage syst
 em earthing (equipment grounding) and protective (equipment grounding) con
 ductor sizing methods are discussed along with the loop current and touch 
 voltage calculations.\n\nAbout the Speaker:\n\nDr. Liu has more than 40 ye
 ars’ experience in electric power engineering. He received his PhD from 
 the University of Wisconsin\, Milwaukee. Before joining ETAP\, Dr. Liu was
  with Cooper Power Systems as a senior power engineer. He is now a Senior 
 Principal Electrical Engineer and has been with ETAP for 23 years. Dr. Liu
 ’s research interest includes electric power system modeling\, simulatio
 n\, and software development. Electric safety has been one of his main res
 earch areas. Dr. Liu is a registered Professional Electrical Engineer in C
 alifornia. He is an IEEE PES and IAS senior member.\n\nVirtual: https://ev
