Current transformer assembly for use with electrical monitoring systems and methods of assembling same

An electrical monitoring system for monitoring an operation of an electric motor, said electrical monitoring system comprising:

• an electric current monitoring device;
• and
• a current transformer assembly coupled to the electric motor, said current transformer configured to sense an electric current channeled to the electric motor and to transmit a signal indicative of the sensed current to said electric current monitoring device, said current transformer assembly comprising:
• a housing comprising a plurality of shielding members that at least partially define a cavity therein, said housing further comprising an inner surface defining an opening extending therethough;
• a first current transformer positioned within said housing;
• and
• a second current transformer positioned within said housing and spaced a distance from said first current transformer to facilitate reducing electronic noise interference between said first and second current transformers.

A method of assembling a current transformer assembly, said method comprising:

• coupling an outer shielding member to an inner shielding member to form a housing, wherein the outer shielding member is coupled radially outwardly from the inner shielding member such that a cavity is defined between the inner and outer shielding members;
• coupling a first current transformer within the housing cavity;
• and
• coupling a second current transformer within the housing cavity such that the second current transformer is spaced a distance from the first current transformer to reduce electronic noise interference between the first and second current transformers.
