ELECTRICAL TRANSMISSION SYSTEMS
We offer consulting services and provide electrical studies, fault simulations (short-circuit), and coordinating protections services for electrical equipment in substations and transmission lines. Our approach is to evaluate system conditions and multiple operating scenarios with credible contingencies to make recommendations for the adjustments of the relay settings electrical protections based on best engineering practices and simulations observations. We also perform impact studies on transmission system protection due to new generation interconnected plants. It should be noted that we have practical experience in studies and analysis in electrical systems up to 500kV.
