SUMMARY

This discussion focuses on generating lightning spike signals in COMSOL Multiphysics for grounding analysis. The user is working on a master project that involves simulating the effects of lightning on materials and grounding rods. Key points include the need for understanding source voltage and impedance models for lightning sources, as well as familiarity with industry standards such as EN-61000-4-5 for immunity testing.

PREREQUISITES
  • COMSOL Multiphysics software proficiency
  • Understanding of grounding rod applications
  • Knowledge of lightning strike modeling techniques
  • Familiarity with EN-61000-4-5 test standard
NEXT STEPS
  • Research lightning strike modeling in COMSOL Multiphysics
  • Explore grounding rod simulation techniques in COMSOL
  • Study the EN-61000-4-5 standard for immunity testing
  • Investigate source voltage and impedance models for lightning simulations
USEFUL FOR

Hello i am new user of in this forum...
i am working on COMSOL Multiphysics for my master project
i am working in the area of grounding so i have to analyze the material with lightning effect so i want to know how i can generate the lightning signal in COMSOL and how we apply to grounding rod

Welcome to the PF. What can you show us of your work and research so far? What models are you considering using for the source voltage and source impedance for the lightning source? There are also some lightning strike standard test procedures that are used in the industry for immunity testing, like EN-61000-4-5. Are you familiar with that test standard?
 
Recently i see these standards but i stucked these types of spike in COMSOL Multipyscis and also how i apply to the grounding rod
