Presentation: Zone Selective Interlocking (ZSI) has existed for more than 40 years, yet many professionals in the electrical industry have little knowledge about what it is and how it works.

ZSI is a network of two or more interconnected circuit breakers that communicate with each other so that a short circuit or ground fault will be cleared by the breaker closest to the fault in the minimum time possible. The primary goal of ZSI is to switch off the fault current within the shortest possible time with full selectivity, regardless of the fault location in an electrical distribution system.

ZSI provides the complete range of selectivity with an extremely short delay time typically of 50ms regardless of the number of fault zones and the location of the short circuit or ground fault in the power distribution system. The benefits of ZSI become more apparent with the higher number of fault zones typically found in large systems.  By shortening the time to clear the fault, ZSI significantly reduces stress and damage in the event of a short circuit. 

Topics to be covered:
1.    Applying ZSI in Arc-Reduction and Selective Coordination circuits
2.    How breakers communicate and connect
