![]() It is the primary resource to calculate short-circuit currents, determine selective coordination and, ultimately, calculate incident energy.The original design drawings revised to reflect changes made in the field are created.A contractor installs an SLD, marking-up the SLD as changes are made.The engineer creates assumptions used to estimate fault-current calculations and selective coordination needs.A design engineer lays out the components and devices to be installed.When using the symmetrical components method, separate one-line diagrams are made for each of the positive, negative, and zero-sequence systems.Īfter the construction of a building is completed, engineers and the builder work together to eliminate hazards related to power supply.So, here the SLD is used along with notational simplification. There can be asymmetric faults on one or two phases. In a three-phase power system, each phase is considered separately as long as the load is balanced separately in each phase.It works differently in a balanced and unbalanced system.
