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, […]

By comparison with busbar type current transformer (CT), the structure of ring type current transformer is simple. Usually, there is a through-hole of no less than 8mm diameter, which allows the primary wire or copper busbar come through. The through-hole may be “I” type or “+” (cross) type, which can fix the busbar properly and make it’s very easy to […]

A miniature current transformer which consists of a busbar and a coil is easy to assemble in an electricity meter or other devices. We can make such kind of component by integrated the ring-type current transformer with a U shape metal rod or plate. Here we introduce each part of a typical current transformer with a busbar. Structure of Current […]

Miniature current transformers (CTs) play an important role in the electrical devices for measurement or protection, such as electricity meters, smart grid, and other electrical instruments. As a professional manufacturer with more than 15 years experience, we introduce the production process of a typical current transformer as below. Of course, different kinds of current transformer may vary a little during […]
