Power Quality Solutions in Central NC

Transformers and panels aren’t supposed to run hot. When they do, it’s usually harmonics. Variable frequency drives, servers, LED lighting, and other electronic equipment don’t draw current in a smooth sine wave—they pull it in choppy pulses. Those pulses create harmonic distortion that travels back through your electrical system, generating heat in transformers, neutral conductors, and motors. That heat doesn’t just waste energy. It degrades insulation, shortens equipment life, and creates fire hazards. We’ve seen transformers fail years early because harmonic heating cooked the windings. Neutral conductors overloaded to the point of melting. Breakers tripping for no apparent reason because the panel is carrying more current than the nameplate suggests. Fixing harmonic problems requires measuring what’s actually happening in your system. We use power quality analyzers to capture the harmonic content at different points in your facility. Once we know which equipment is generating harmonics and how severe the distortion is, we can recommend filtering, isolation, or system modifications that bring things back to normal operating temperatures.
