How High-Voltage Current Transformers Monitor The Grid

Grid-level current transformers (CTs) enable safe monitoring of extremely high voltages and currents, often 5 kA and above, by providing galvanic isolation between the power lines and measurement equipment. CTs support over-current protection, over-voltage protection, and differential protection to detect leakage, shorts, winding damage, or illicit power tapping. An explainer video by Jordan Taylor (The Electric Brit) covers the engineering challenges involved, including imperfections like core saturation and the importance of selecting the right transformer type for accurate readings.
