摘要

? 2022 Elsevier B.V.In low voltage systems, the flexibility of their handling by unqualified personnel causes countless electrocutions, sometimes resulting in human death. The current generated in low voltage with demands up to 12 kVA in the main distribution board and its easy access to its manipulation has led to the study that proposes to implement coordination of actions to protect people's lives. For this purpose, case studies implemented the different configurations of the protection devices test, the case relay–relay–fuse configuration with variation in the length from the distribution transformer to the load. The relay–relay–relay behaviour is located at an average distance from the distribution transformer to the load. Different randomized scenarios were recreated to find the most optimal solution, optimally coordinate the protection devices, and thus protect human life.
