Automotive, industrial, and FireWire peripherals all call for high-efficiency, space-saving power supplies with high current capabilities at very high voltages. The problem is that high-voltage, ...

Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

Here’s a handy little current source that’s often used to control the current flowing through a load. Find the equation that defines the i-Load current and account for non-ideal sources. The i-Load ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

The ACB technology, coupled with load current monitoring, remote diagnostics and visual indications, ensures maximum reliability in redundant power systems. the technology automatically and ...

A 480V, 3-phase, squirrel-cage motor is a common piece of equipment in many facilities. When sizing circuit breakers, fuses, and conductors for a general AC motor branch circuit, National Electrical ...

For modern distribution protection, Negative Phase Sequence (NPS) Protection is often relegated in favor of common elements such as Overcurrent (OC) or Earth Fault (EF), but NPS is an incredibly ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...
