Power Factor in Networks Power factor is a measure of the phase difference between the voltage and current in an AC power system. In purely resistive loads (such as an incandescent lightbulb or electric kettle) the current is in phase with the voltage and there is ‘unity’ power factor. Capacitive and inductive loads (such as a capacitor banks or inductive motor respectively) will cause...
Why is load balancing important in 3-phase networks? It is just as important to balance single phase loads as it is three phase loads. The grounded circuit conductor (neutral) carries all unbalanced current. If the imbalance is greater than the neutral,it could become overloaded, heat up and start a fire. There is no over-current protective device for this conductor. If you buy a transformer with ...
Power Factor Correction and Reactive Power Compensation Power Factor Correction(PFC) is done by electricity consumers to avoid penalties on account of large KVA demand or lower power factor. Normally, such penalties are imposed on industrial consumers. Therefore, industries need more lagging KVAr due to induction motors or otherwise, install capacitors banks or Static Var Generator(SVG) for power ...
Over its 100-year history, welding has become one of the most essential technical skills in manufacturing and fabrication. The process of using high-temperature, electrical-powered heat to fuse two pieces of metal or synthetic material has been incorporated throughout the industry in an increasingly wide variety of applications that rely on a range of tools and techniques. But Electrical welding m...
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. ...

Since we worked with Australian clients, they have build Static Var Generator(SVG) panel, Active Harmonic Filter(AHF) panel, and hybrid SVG and AHF panel. This customer's visit gave...
Backgaround With the development of the economy and the improvement of green energy awareness, more and more regions are using clean energy and installing a large number of solar power generation equipment. With the widespread use of photovoltaic power generation, many users have found that there are power adjustment fees, namely power fines, in the electricity bill, and the amount of fines is rel...
