What are scenarios causing power factor displacements 1. Poorly designed electrical systems with inadequate power factor correction equipment. 2. Large inductive loads such as motors, transformers, and generators that cause lagging power factor. 3. Unbalanced three-phase loads that cause phase displacement of the current and voltage waveforms. 4. Unbalanced single-phase loads that cause current an...
Reactive currents backstreaming from Solar to Utility Reactive currents backstreaming(from Solar plant) in power supply system is not only harmful but also expensive for financial purposes. Parasite currents in both electricity transmission lines and equipment of solar power-stations cause financial losses because of converting electric energy to thermal (thus making generation amount lower, that ...
Power Quality Power electronics make modern life possible and enable all other areas of innovation. Although stable power delivery seems like a simple problem, the design of a high-efficiency power transmission and conversion system is prone to several problems that reduce efficiency by reducing delivered power. Nonlinear components are needed in power electronics to control the flow of power and ...
Microgrids are designed to operate at a fundamental frequency (50 or 60 Hz). However, certain types of loads generate voltage and/or current harmonics that increase power system heat losses. These harmonic losses reduce system efficiency, cause apparatus overheating and increase power costs. Besides that, the Distributed Generation (DG) is expected to play an important role in future power systems...
Achieving capable factory functional test requires meeting multiple criteria to ensure the highest quality product. These criteria include test capability and repeatability, system upgradability and supportability, and production scalability. Setting up new production test not only involves implementing new test systems, but also managing schedule risk and budget which are often impacted by techni...
Power factor is a measurement of electrical system efficiency. Many utilities have a power factor penalty built into their rate structure to penalize users with a low power factor reading in their electrical system. To improve the power factor, the most common solution is to install a capacitor banks, But Static Var Generator is the best power factor correction product. There are 3 kinds of...
