Relay protection system risk management depends heavily on how the relay room is designed, controlled, and maintained. Environmental stability, redundancy architecture, cybersecurity, and maintenance accessibility directly affect whether protection systems operate correctly. PG&E developed Enhanced Powerline Safety Settings (EPSS) to help reduce wildfire risk by adjusting the sensitivity and speed of protective devices such as circuit breaker relays and reclosers. As currently implemented, circuits enabled with EPSS are configured to clear bolted fault conditions at. Safety Precautions for All Relays Refer to the Safety Precautions for individual Relays for precautions specific to each Relay. INTRODUCTION AND BACKGROUND The potential for electric overhead power lines to provide an ignition source for wildfires has prompted utilities to change long held protection strategies that were implemented to minimize outages and implement strategies.

While PPE protects for first and second degrees burns it does not provide suficient protection for the impact and forces that a high incident energy arcing fault produces and the gases released. One solution is to reduce the incident energy of the arcing fault.
