Significant advances in high-voltage direct current (HVDC) transmission are in step with rapid changes to energy systems worldwide. Shortly after POWER magazine began publication in 1882, the ...

Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

As part of the move to increase efficiency, power supply units are moving from the bottom trays to their own racks.

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

There are various reasons why you might need to split a voltage rail in your design. Perhaps the design contains a sensor or an IC that requires a bipolar supply, or you need to make the best use of ...

Voltage references are available with fixed and adjustable reference voltage outputs. Adjustable output is set by a resistor divider connected to a reference pin. These references are either shunt ...

High-voltage power transmission systems are more important today than ever before because power generated at renewable energy sites in remote locations must often be transmitted to distant load ...

Discover why impulse voltage insulation class (IVIC) is critical when selecting IEC motors for converter duty.

James Gibert, associate professor of mechanical engineering, and Hongcheng Tao, postdoctoral researcher, observe their test apparatus as it generates an electric charge by rubbing two surfaces ...

Lead times for medium- and low-voltage (MV/LV) switchgear, transformers, and other major pieces of electrical infrastructure ...
