We perform three-phase fault simulations, line to ground fault, line to line fault and line to line to ground fault. To know the short circuit currents at each point of the system.
In order to perform the Arc flash study, it is necessary to have previously performed the short circuit study. In turn, for the coordination of protections it is necessary to know the short circuit level.
We perform three-phase fault simulations, line to ground fault, line to line fault and line to line to ground fault. This allows us to know the short circuit currents at each point of the system, for half-cycle and 5-cycle asymmetrical currents, as well as initial and steady-state symmetrical currents.

When starting an installation it is necessary to perform a short-circuit evaluation to know the capacities of the equipment to be installed. In addition to determine the fuses and thermomagnetic switches required for proper operation.

This risk assessment analysis complements the scopes of the Protection Coordination Study. It evaluates the conditions of the power plant according to NFPA 70E-2018 standards.

By performing this simulation we can know the amount of energy that passes through our installation in case of three-phase faults, line to ground fault, line to line fault, line to line to ground fault.
By knowing the values of the cables, installed equipment and current contribution of CFE we can calculate the amount of short-circuit current that will pass through each point where there could be a fault.
Based on this analysis we choose the ideal protection equipment to protect your installation according to ANSI / IEEE C37, NOM-001-SEDE-2012 and UL 489 standards.
