Paper Subject

Where Presented

Transformer Overcurrent
Protection Coordination
This paper presents a tutorial with information drawn from C57.109 and C37.91 highlighting the damage curve development and its use for different transformer MVA capacities. Also discussed are the effect of different winding configurations on coordination 69th Georgia Tech Protective Relay Conference, April 29 - May 1, 2015.  Atlanta, GA
Directional Comparison Blocking
System Fundamentals
The paper addresses the operational concept of the DCB scheme using “on/off” power line carrier, and issues pertaining to reliability and performance. This includes the pros and cons of using “non-directional” or “directional” start of the blocking signal, the blocking coordination timer, carrier hole issues and mitigation, and relevant logic 39th Annual Western Protective Relaying Conference October 16-18, 2012.  Spokane, WA.
