Computer Simulation of Grounding Applications

Computer simulation of grounding applications are important for power generation and distribution. INTEGRATED’s proprietary Boundary Element Method (BEM) solver simulates various types of grounding scenarios very efficiently, especially in the HVDC domain of power/energy industries and in applications involving open regions for electromagnetic field computations.

Below is a case, where INTEGRATED’s COULOMB has been used to simulate a HVDC grounding system. The model consists of 648 volumes, which have been assigned specific conductivities....
