Fault detection in transmission networks of power systems

International Journal of Electrical Power & Energy Systems, 2011
Abstract An online fault detection scheme for a sample power system is introduced in this paper. The detection approach is based on the use of a variable structure system called “sliding mode observer”, where information contained in the output measurements is utilized to detect the onset of faults in the transmission network of the sample power ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Development of Fault Characterization Equipment (FCAREC) for Power Transmission Lines

IEEJ Transactions on Power and Energy, 1992
The authors present fault characterization equipment (FCAREC) which detects fault resistances in a time sequence, in addition to the conventional determination of fault location. The objective of FCAREC is to offer improved functions to estimate causes of system faults.
