Ground Fault Protection & Protection Coordination in Industrial & Commercial Power Systems

This webinar is taught by Claudio S. Mardegan of Engepower in Brazil. He will dicsuss the importance of calculated bolted and arcing fault, and why this value shall be as close as possible to the actual value is also discussed. System grounding determines the system behavior and sometimes you may think you are grounded but you are not. He will also talk about escalation of single-line-to-ground arcing faults, types of protection coordination, coordination time interval (CTI) determination, and where to apply CTI general rule and particularities. Finally, he will discuss overcurrent optimized setting, phase protection as back of ground single line-to-ground protection, and coordination of voltage relays with overcurrent relays.
