Split Core Current Transformer, 10A AC, 90mm

Dimension Unit (mm)

Q1: What is a split-core current transformer?
A1: Split core current transformer is made of high strength PVC shell, fully cast busbar type structure. a split core current transformer is directly stuck on the cable with three sexual rubber rings against the cable and the cable one. The transformer core uses better silicon steel rolled, the secondary wire evenly wound in the core. Transformers for the open and closed structures can be installed without cutting the cable.

Q2: What is the meaning of the circles of the split core current transformer?
A2: On electrical system diagrams, a small circle is often used to represent a winding, and a circle is used to represent a winding. If you have two circles in a series, that means that the open and closed current transformer has two windings. If you have three circles in a series, that means you have three windings.

Q3: What is a split core current transformer error?
A3: Due to the structure of the split core current transformer core and material properties, the current transformer has an excitation current I0, which makes it produces errors.

Tips: What is the rated current of split-core current transformer?

Primary rated current: the load current allowed to pass through the primary winding of the current transformer. The primary rated current of current transformer used in power system is 5～25000A, and the precision current transformer used in testing equipment is 0.1～50000A. Current transformer can operate under the primary rated current for a long time, when the load current exceeds the rated current value, it is called overload, and the long-term overload operation of current transformer will burn out the winding or reduce the service life.
