1. A current transformer comprising:
a body having an upper half and a lower half hingedly connected to the upper half;
a pair of ferrite cores located within one of the upper half and the lower half of the body, the pair of ferrite cores defining a gap formed between each ferrite core of the pair of ferrite cores;
a hall-effect sensor located within the gap formed between each ferrite core of the pair of ferrite cores; and
a memory storing a software configurable register,
wherein the register includes a pre-determined scaling factor associated with the pair of ferrite cores and the sensor, the pre-determined scaling factor being determined by pre-calibrating the current transformer using a simulated test current.
