Voltage and Current Excitation for Time-Harmonic Eddy-Current Problems [PDF]
SIAM Journal on Applied Mathematics, 2008 We give a systematic presentation of voltage or current intensity excitation for time-harmonic eddy-current problems. The key point of our approach resides in a suitable power law that permits us to understand the role of voltage excitation. We also shed light on the influence of the boundary conditions on the proposed formulations.

Bispectrum of stator phase current for fault detection of induction motor [PDF]
, 2009 A number of research studies has shown that faults in a stator or rotor generally show sideband frequencies around the mains frequency (50 Hz) and at higher harmonics in the spectrum of the Motor Current Signature Analysis (MCSA).

Harmonic assessment‐based adjusted current total harmonic distortion
The Journal of Engineering, 2016 Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency‐dependency of the resistances should be taken into account, so that the apparent power and the power factor have to ...

Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]
, 2012 We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...

Coordinated control for harmonic mitigation of parallel voltage-source inverters
CES Transactions on Electrical Machines and Systems, 2018 The increasing use of power electronic devices can deteriorate the power quality by introducing voltage and current harmonics. In islanded microgrids, the presence of nonlinear loads can distort the point of common coupling (PCC) voltage, while the dead ...
