Power feels simple until voltage has to travel hundreds of miles. Then losses rise, outages happen, and equipment fails. A transformer solves this by changing voltage safely and efficiently. Transformers let the grid move power at high voltage and low current for long distance, then step it down in layers so people and equipment can […]

Are you wondering what those gray boxes on utility poles are? They seem complex and mysterious, but their job is simple. Here’s the straightforward explanation you’ve been looking for. A transformer is a static electrical device that changes the voltage of an Alternating Current (AC). It steps voltage up for efficient long-distance transmission and steps […]
