The Journal Magazine from Rockwell has an article called, "Stopping Arc Flash In Its Tracks."
The article discusses a number of equipment design strategies for stopping or reducing arc flash. These include:
- Shielding Against Arc Flash - building strong cabinets
- Limiting the Available Current using current-limiting fuses or fast-acting circuit breakers
- High-Resistance Grounding (resistance grounding system)
- Arc Flash Relays use photodetectors to detect light from an arc that is starting to form.
