Abstract: A transformer that comprises a winding assembly, a first and a second output terminal and a first and a second conductive path. The winding assembly includes a first and a second winding assembly terminal, a winding coupled between the first and second winding assembly terminals, and a resistive load coupled between the first and second winding assembly terminals. The resistive load has a resistance and an intrinsic inductance effectively in series with the resistance. The first conductive path connects the first winding assembly terminal and the first output terminal. The second conductive path connects the second winding assembly terminal and the second output terminal. The first and second conductive paths enclose an area through which magnetic flux can pass so as to provide a pickup loop inductance between the first and second output terminals.

Abstract: A current transformer for monitoring a current in a conductor. The current transformer comprises a winding assembly that includes a resistive load. The transformer further comprises a compensation circuit that has an impedance selected to reduce output signal overshoot across the output terminals of the current transformer caused by the intrinsic inductance of the resistive load. The transformer also comprises a small gauge semi-rigid coaxial cable to reduce a loop pickup area formed by the conductive paths that connect the winding assembly terminals of the winding assembly and the output terminals of the current transformer. This results in output signal overshoot across the output terminals being further reduced. Additionally, the transformer comprises a transformer shield that encloses the winding assembly and has end portions that do not contact each other to define a gap that prevents the transformer shield from acting as a shorted turn.

Abstract: An attenuator for use with a current transformer. The attenuator includes an input voltage terminal, an input ground terminal, an output voltage terminal, an output ground terminal, an input resistive arm, a shunt resistive arm, an output resistive arm, and a compensation circuit. The input and output ground terminals are coupled together. The input resistive arm has a first end coupled to the input voltage terminal and a second end. The output resistive arm has a first end coupled to the output voltage terminal and a second end coupled to the second end of the input resistive arm. The shunt resistive arm has a first end coupled to the input and output ground terminals and a second end coupled to the second ends of the input and output resistive arms. The shunt resistive arm has a shunt resistance and an intrinsic inductance effectively in series with the resistance.
