mounting portion 16 and mounting recess 30 in line side mounting portion 18 are provided so that each of the mounting portions 16 and 18 can be securely mounted to any desired surface such as a line side bus or a load side bus as described earlier it will be appreciated that the conductor of the current transformer assembly is formed by connection between the load side mounting portion 16 load side screw fastener 24 body portion 14 line side screw fastener 26 and line side mountain portion 18 such assembly creates a securely connected and high quality electrical conductor it also at the same time provides a sturdy mounting structure for the toroidal core 12 in such a way as to protect the various windings around the toroidal core from damage these benefits are achieved at a low cost by using standard components and stock material such as standard sized copper sheet stock copper rod or tube and off the shelf fasteners although a wide variety of fastener materials can be used the screw fasteners 24 and 26 are preferably silver plated or otherwise plated metallic screws each of the conductor components is preferably plated with silver or another conductive material to ensure adequate electrical connection referring now to fig3 a and 3b another embodiment of a current transformer assembly according to this.
