Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system. These inrush currents can cause sags ...

Digi-Key, in collaboration with Ametherm, presents a PTM describing transformer protection from inrush current using the NTC thermistor. This will provide a problem statement describing the inrush ...

A simple approach based on original research attacks inrush currents at the source - the power transformer. The use of special core materials and transformer design/construction techniques overcomes ...

Nov. 13, 2008, PULLMAN, WA - Schweitzer Engineering Laboratories, Inc. (SEL) is now taking orders for two new products, the SEL-787 and SEL-487E Transformer Protection Relays. These are the first ...

This month in EC&M's forum for your power quality questions, Mark McGranaghan, vice president of consulting services, teams up with several other experts from EPRI-PEAC to address the topics of ...

However much care is taken, it is very difficult to keep all traces of transformer-induced hum out of the signal circuitry. It is highly irritating to find that despite the cunning use of low-noise ...

In part 1 of my blog, we looked at the capabilities that the EDA tools provide in the area of supply network analysis. Now, we look at the different methods of power shut off control in the supply ...

Bulk capacitors typically require a large amount of current to charge up, resulting in a large inrush current. However, thanks to a unique control algorithm, an innovative inrush-current control ...

Achieving UL recognition for the SL2220007 is an important milestone that underscores our commitment to delivering high ...
