One of the most dangerous locations in a power distribution system with regard to incident energy is that first panelboard on the secondary of a transformer. With some thought in your design — even if ...

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 ...

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 ...

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 ...

Offline power supplies that drive loads of 200W and more require inrush-current limiters. Unrestricted inrush currents can reach hundreds of amperes, which may damage the line rectifier, open the fuse ...
