A current transformer includes a pre-formed core forming a closed loop with a flexible axially wound secondary winding. A continuous length of wire is axially coiled around a flexible bobbin to form a secondary winding. The resulting secondary winding may be slid onto the closed loop of the ...
The zero sequence current transformer is full enclosed type. The invention discloses a current transformer, which comprises a primary coil, a secondary coil, an iron core and a shell. The excitation characteristic of secondary winding of current transformer is the key factor to transformer performanc...
The basic structure of the current transformer is mainly composed of a primary winding, a secondary winding and an iron core, and there is insulation between the primary, secondary and iron cores. The simplest current transformer has a primary winding, a secondary winding and an iron core. Such...
