Analyse of harmonic distortion in power systems consists in the determination of steady state quantities for each harmonic component at a time. The existing theoretical relationships are difficult to be implemented in complex systems containing many elements, in various combinations. In the case of radial power systems operated in sinusoidal conditions, the load flow calculation can be performed using...
Besides industrial or domestic customers, some single-phase distributed generators can impose an unbalanced operation of electrical networks. In the case of balanced power systems operated in radial schemes, the load flow calculation can be performed using a particular method known as the backward/forward sweep. For unbalanced radial electrical networks, we can consider the backward/forward sweep...
For harmonic polluted electrical networks, the load flow calculation consists in the determination of steady state quantities for each harmonic component at a time. On the other hand, the load flow calculation for unbalanced/asymmetrical electric networks consists in the determination of steady state quantities for each phase at a time. The theoretical relationships proposed in literature are complex...
A new method for water determination of latex paints that gives reliable and precise results is presented. This method agrees with the results obtained using the traditional Karl Fischer titrations of EPA Method 24; therefore eliminating the need for Karl Fischer titrations. Equipment needs are minimal and the procedure is performed quickly and conveniently. Hopefully, in the future EPA Method 24...
