What is selectivity?
The electrical design industry has historically required electrical system circuit breaker selections and settings be validated with a short circuit and coordination study performed by a licensed engineer. These studies assure that circuit breakers are capable of interrupting the available current and would operate “selectively”.
Traditionally, “selectivity” in a low voltage electrical system meant that the long time and short time portions of time-current curves (TCCs) would be selective, i.e. the circuit breaker closest to the fault would trip first, maximizing the amount of the electrical distribution system left in service
In most cases, the circuit breaker instantaneous overcurrent (IOC) TCCs would not be selective “on paper,” as they typically overlap.
Traditionally, selectivity between molded case circuit breakers (MCCBs) and insulated case circuit breakers (ICCBs) was considered effective, even if there was an overlap of TCCs in the

The program WinIGS performs analysis and design of a grounding system or multiple grounding systems that are an integral part of an electric power system. Specifically, it allows the user to model any power system together with its grounding structures, it analyzes the performance of the system under steady state, normal, and fault conditions, and evaluates its performance against industry-standard criteria. The user may select either the IEEE Std. 80 criteria or the IEC-479-1 criteria, both of which have been integrated into the program.
The power system network data as well as the grounding system geometric data are edited via specialized GUI based editors, which are tightly integrated into the WinIGS program. Specifically, the network data are edited via a network editor, which displays the power system in single line diagram form. The network topology can be manipulated using the mouse. Device parameters can be accessed by double clicking on the device drawing. Analysis results, co
