Current Transformer Dc Saturation at Carmen Wong blog

Current Transformer Dc Saturation. It is very important to analyze the behavior of a current transformer for its applied primary current, which may contain large magnitude alternating. The purpose of a current transformer (ct) is to produce an exact replica of the primary current waveform with its. Dc offset in the primary current. The maximum dc offset will occur when the fault is applied at a voltage minimum (t=0.49167 s). The excitation current increases exponentially after 110 % nominal voltage is applied. The increased excitation current causes overheating of the core and can cause permanent damage. If you terminate your current transformer with a resistor to get a voltage signal out, a normal ac current transformer would saturate very quickly if you apply any dc. Core saturation in the transformer causes increased thermal stress on the transformer.
