IntroductionReview of the Design/Installation Process

A case study of a medium voltage breaker

A case study of a transmission breaker

A case study of a control IED as a transformer alarm aggregator

Page 4: Utilizing IED Capability to Reduce Wiring Terrence Smith, GE Digital Energy Multilin Richard Hunt, GE Digital Energy Multilin Jakov Vico, GE Digital Energy

IntroductionA case study of a high voltage circuit breaker using process bus.

A look at the direction the industry will likely head.

Rules we can develop from the case studies.
