Third harmonic current minimization using third harmonic blocking transformer
Indonesian Journal of Electrical Engineering and Computer Science, 2022 Zero sequence blocking transformers (ZSBTs) are used to suppress third harmonic currents in 3-phase systems. Three-phase systems where single-phase loading is present, there is every chance that the load is not balanced. If there is zero-sequence current due to unequal load current, then the ZSBT will impose high impedance and the supply voltage at the

Examples of Minimal Laminations and Associated Currents [PDF]
, 2010 In this paper, we construct various examples of holomorphic laminations, with leaves of dimension 1, and we also study some of their dynamical properties. In particular we study existence and uniqueness of positive closed currents.

Harmonic Current Predictors for Wind Turbines
Energies, 2013 The harmonic impact caused by wind turbines should be carefully investigated before wind turbines are interconnected. However, the harmonic currents of wind turbines are not easily predicted due to the variations of wind speed.

Ergodicity of laminations with singularities in K\"ahler surfaces [PDF]
, 2013 If $\mathcal{L}$ is a laminations with hyperbolic singularities, embedded in a compact homogeneous K\"ahler surface, without directed closed positive currents. Then, $\mathcal{L}$ has a unique directed positive harmonic current of mass one.

Heat transport in harmonic lattices [PDF]
, 2006 We work out the non-equilibrium steady state properties of a harmonic lattice which is connected to heat reservoirs at different temperatures. The heat reservoirs are themselves modeled as harmonic systems.

Observation of second-harmonic generation induced by pure spin currents [PDF]
, 2011 Extensive efforts are currently being devoted to developing a new electronic technology, called spintronics, where the spin of electrons is explored to carry information. [1,2] Several techniques have been developed to generate pure spin currents in many
