Core Loss and Copper Loss in Transformer
Every kind of electrical equipment will happen to power loss occurs during long time operation, and the transformers are no exception. As the main equipment for voltage transform and power transmission, transformers are widely used in Power Grid. These power losses are mainly divided into copper loss (load loss) and Iron loss (core loss) Copper loss When someone in electric industry says copper, many people may think of copper wire. In fact, he copper in the copper loss of the transformer also refers to copper wire. Most transformer windings are made of copper wires. Generally, the number of turns is large, so the resistance will not be ignored, and the […]

Why Are Designs in Current Transformers Important for Electrical Accuracy and Safety?
Current transformers (CTs) are often small in size but play an essential role in power systems to be compromised by their apparent inconspicuousness. They form the basis for safe monitoring and the accurate measurement of high-voltage currents, especially in industrial and utility-scale electrical systems.
