Miniature Current Transformer
In order to make a customized current transformer, some important parameters should be specified by the clients in advance. Max. Current The measurement range of a mini current transformer is specified by its max. current. Within the range, the secondary current is proportional to the primary current. Turns Ratio For mini current transformer, typical turns ratios are 1:1000, 1:2000, 1:2500, […]

Enamel wires are critical materials for miniature current transformers. The basic parameters of the most popular used enamel wires are introduced as below. The diameter of bare core range from 0.10mm to 0.31mm. For a typical mini current transformer of 10(100)A/10mA with turns ratio 1:1000, the enamel wire of Φ0.18mm is suitable. For some CT with rate current > 200A, […]
