Wandler-Check: 1A + 1A + 1A = NULL? 🤯

Welcome, dear friends of protection, control, and electrical engineering. In one of our recent training sessions, our participants were asked the following question: Three symmetrical conductor currents, each with a value of one ampere, flow through a cable-mounted current transformer in a perfectly symmetrical arrangement: L1 at 0°, L2 at -120°, and L3 at +120°. What is the current measured at the secondary terminal if the transformer has a conversion ratio of 60/1 A? The answer is in the video! Enjoy watching! Your ENGINEERING ACADEMY®
