Abstract

In this research, a study was conducted to re-evaluate the safety levels of the grounding system for the Mosul Secondary University distribution station, by taking the effect of the conductors of the foundation arming grid on the electrical potential distribution resulting from faults to the grounding system implemented by the Lebanese company (MATELEC s.a.l). A fault current of (20kA) was adopted. The CYMGRD program was used to re-design the grounding system implemented by the company in two stages, first without taking the effect of the arming grid of the foundations, and then the grounding system was redesigned by adding the arming grid of the foundations implemented inside the concrete and linking it with the basic grounding system that was formed of conductors and grounding rods, and the results showed the significant effect of the foundation arming grid in reducing the levels of touch voltage (Em) by 33%.
