Have you ever wondered what makes a loudspeaker “difficult to drive”? Do you wonder what’s so special about an amplifier that is stable into a 4 ohm load? If these are the kinds of questions that ...

You can't avoid power line disturbances altogether, but you do have access to options for mitigating voltage, current, and frequency deviations produced by the electric utility system. You can ...

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 ...

Welcome to my first blog post that explores fundamental principles of electrical engineering and attempts to tease out some new insights. For many of you, this will be a refresh of concepts you ...

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 ...

Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...
