The primary winding structure of the current transformer has two forms of single-turn type and multi-turn type. Single-turn type: The winding is only one turn at a time, and the structure is relatively simple. The primary current is more than 300 to 600A. It is divided into two types: bar type and bus bar type.…
DetailsCurrent transformer is mainly composed of a primary winding,a secondary winding and an iron core, and there is insulation among the primary, secondary and iron cores. In order to improve the accuracy of the current transformer, the error of the current transformer is generally compensated.In addition to the above-mentioned primary and secondary windings and cores,…
DetailsThe current transformer is very similar to the transformer. The transformer is mainly used to change the voltage of the line on the line, while the current transformer is mainly used to change the current of the line. Why do we need variable current on the line? This is because according to the different conditions…
Details[vc_row][vc_column][vc_column_text]A Rogowski coil is an electrical device for measuring alternating current (AC) or high-speed current pulses. It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil. The whole…
DetailsAs the saying goes: nothing is new under the sun. Regarding this proverbs, there are two factors I may consider. For one thing, all things exist on the earth are rely on the solar energy to some extent, even the conventional resource such as coal, fossil and petroleum are indirectly produced by solar energy. For…
