This is particularly true of generator differential relaying ... even for as short a time as one cycle with a high-speed relay, the relay problem becomes one of properly discriminating between a false ...

This article attempts to set forth something of the nature of these split-phase currents and discusses the type of current transformers and relays which can be used to afford generator winding ...

Loss of excitation (LOE) protection ... generator's response to LOE events. The method has shown improved reliability and ease of implementation compared to traditional impedance-based relays ...
