ger3055Consideration of Speed, Dependability, and Security in Pilot Relaying Schemes02/19/1998 [354k]
ger3224High-Speed Reclosing System and Machine Considerations01/30/1998 [299k]
ger3735Relaying Short Lines07/21/1997 [159k]
This paper will present a brief overview of some advantages and disadvantages of both current only schemes and distance/directional schemes, as well as some of the problems that may arise as the source to line impedance ratio increases.
ger3742Dynamic Characteristics of Mho Distance Relays02/17/1998 [202k]
This paper describes the dynamic characteristic of phase mho relays which use the faulted phase voltage as the polarizing quantity, and which have 'memory action' in the polarizing circuit.
