ABB said it has successfully developed and tested an 1100 kV "ultrahigh-voltage" direct current converter transformer, breaking the record for the highest DC voltage levels ever, and facilitating more ...

In high voltage applications involving tens of thousands of volts, too often people think about the high voltage needed but don’t consider the current. This is especially so when part of the circuit ...

Instrument transformers provide reliable and accurate input for the protection, control and monitoring of power grid assets such as motor control centers, UPS systems, utility metering, low and medium ...

It’s not just red tape that’s limiting the supply of electricity in America. Grids are physical machines, and they’re short ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

A transformer transfers electrical energy from one system to another by induction. Except for grounding and bonding connections, there’s no physical connection between the two systems. For this reason ...

Thomas Edison championed direct current, or DC, as a better mode for delivering electricity than alternating current, or AC. But the inventor of the light bulb lost the War of the Currents. Despite ...
