This course will cover the application of three different technologies. This includes ultra-fast grounding switches which detect and kills an arc flash incident in 4 milliseconds. This encompasses incident energy calculations, and the factors considered in IEEE 1584 2018. Examples of electrode configurations, orientation, and calorimeter positioning will be explained. Also, arc flash boundaries and arc flash mitigating techniques will be detailed.
The second technology is the electronically triggered fault current limiter (ET-FCL). This device can detect and interrupt a circuit in 0.6 milliseconds, as compared to a three- cycle circuit breaker which trips in 50 milliseconds, thus avoiding equipment damage and serious injuries.
The third technology is the transient-free capacitor switch which avoids creating overvoltage, inrush current, and the possibility of restriking during the process of opening the switch.
