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...
Capacitive reactive power The reactive current of the load is generally inductive, so we can use capacitor bank to compensate it. However, the reactive power generated by loads such as UPS and charging pile is capacitive. Capacitor banks cannot compensate capacitive reactive power, so the latest reactive power compensation technology SVG Static var generator needs to be used to compensate cap...
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...
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 ...
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. ...
For all clients, We adhere to quality-oriented, try our best to meet customer's technical requirement. Our client also has a good,professional technical team, they buy our modules to build cabinet locally in Australia. 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...
