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...
Electricity is generated by generating stations and transmitted to load centers from where it is distributed to end consumers. These load centers are controlled by distribution utilities, and there is an inter-change of energy between different utilities connected to the grid. Consumers connected to the distribution utilities, though consuming active energy may or may not consume reactive energy. ...
Night-Time Reactive Power Management and Ferranti Effect Voltage Control in Long Solar PV Feeder Networks Quick Engineering Answer: In large-scale solar PV farms with extensive medium-voltage (MV 33kV/35kV) underground collector networks (often exceeding 50 km in cumulative length), zero-generation night-time conditions trigger the Ferranti Effect. The distributed shunt capacitance of lightly load...

SMT mounter SMT (Surface Mount Technology) is an electronic component installation technology used to attach electronic components (such as resistors, capacitors, integrated circuits, etc.) to printed circuit boards (PCBs). Compared to traditional plug-in technology, SMT patches have higher density, faster production speed, and lower production costs. The working principle of SMT patches is...
