Automatic detection test of current sensor faults for induction motor drives at standstill

del-Olmo, Jon; Poza, Javier; Ugalde, Gaizka (IEEE, 2016)

This paper proposes an automatic detection test of gain faults in current sensors. An offline test is applied when the machine is not operating. The designed test operates at standstill without being necessary to disconnect ...
DC-link sensor Fault Detection and isolation for railway traction electric drives

del-Olmo, Jon; Poza, Javier; Garramiola, Fernando; Almandoz, Gaizka (IEEE, 2017)

This article presents the design and the implementation of a fault detection and isolation strategy for sensors in variable speed drives. Electric drives use several current and voltage sensors for control and protection. ...
