Selectivity study schneider
WebSelectivity (discrimination) is achieved by automatic protective devices when a fault is cleared by the protection device installed immediately upstream of it, while all the other protection devices remain unaffected. Two areas can be defined, depending on the current ranges and circuit-breaker trip curves: In < I < 8÷10 x In Overload zone WebNov 21, 2024 · Section 536 of BS 7671 now has extensive descriptions of the application of Selectivity between Overcurrent Protective Devices (OCPD), RCDs and other devices. …
