ABB has won orders worth over $100 million to supply converter transformers and components including wall bushings and circuit breakersfor the Lingzhou-Shaoxing ultrahigh-voltage direct current (UHVDC ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

With a primary-current rating of 10A and an isolation voltage of 500 Vdc, the 5600 series current-sensing transformers are capable of both measuring and monitoring ac currents. They are available in ...

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...

A new AC power connection module for near-shore wind turbines is expected to cut the cost of accessing the grid for such installations by as much as 40 percent. This solution from Siemens thus also ...

MR16 halogen lamps normally operate from a low-voltage AC source typically generated by a low-frequency AC transformer or by a high-frequency electronic transformer. In most MR16 applications, the ...
