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...
What is the power quality problems at sites with welding machines? The most common power quality problems associated with welding machines are voltage sags, harmonic pollution, and electromagnetic interference. Voltage sags can cause the welding machine to operate at a lower than expected output, resulting in poor weld quality. Harmonic distortion pollution can cause interference with other equipm...
Site conditions The site is located in Hangzhou Asian Games Village.The project has more than 20 power distribution rooms. Due to the main load being fire-fighting facilities, which are generally not started, the transformers almost all operate without load, and the cable length is long, resulting in capacitive reactive power at both the high and low voltage sides, which cannot be compensated by t...

The reactive power consumed by the transformer is generally about 10% to 15% of its rated capacity, and its no-load reactive power is about 1/3 of the full load. Therefore, in order to improve power factor (PF) of the power system, the transformer should not operate at no-load or in a long-term low-load operation state. Vigorously improving the power factor of transformers, reducing line losses, a...
What are the advantages of YT Static VAR Generator? YTPQC-SVG Static Var Generator is an electronic reactive power compensation system, for both capacitive and inductive power. Our SVG operates by sensing the load current and then injecting or absorbing the reactive power as needed. When the system is capacitive, meaning it produces excess reactive power, YT SVG absorbs reactive power to main...
Hybrid power factor correction refers to a combination of capacitor banks and power electronic converters (such as Active Power Harmonic Filter or Static Var Generator) used to improve power factor and mitigate harmonics in electrical power systems. The advantages of hybrid power factor correction over capacitor banks alone include: Power Factor Correction: Hybrid solutions offer dynamic and preci...
The development of Energy Storage Systems is necessary for a variety of reasons: Integration of Renewable Energy Sources: Energy storage plays a crucial role in the integration of intermittent renewable energy sources like solar and wind power into the electricity grid. These sources produce variable power output based on weather conditions, and energy storage helps mitigate the mismatch between g...
