Someone once asked: how does a\u00a0current transformer<\/strong><\/a>\u00a0work? It is a fair question. The device looks simple. A donut-shaped core. A few wires. But what happens inside is not always obvious.<\/p>

A\u00a0current transformer\u00a0is one of those devices that people use every day without thinking about how it actually works. Meters rely on it. Protection relays depend on it. Energy monitoring systems would be useless without it.<\/p>

This article explains how a\u00a0current transformer\u00a0works. Not just the textbook answer. The practical side too.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
