Non-ideal frequency response (FR) and voltage non-linearity of high-voltage (HV) instrument transformers directly impact the accuracy of HV measurements in the presence of harmonics. Characterization of voltage instrument transformer FR is generally performed at low voltage (LV) with sinusoidal test signals. Those results may not accurately represent the response of the instrument transformer when subjected to distorted waveforms in modern power systems. This article presents a calibration system for the evaluation of harmonic measurement accuracy of single-phase instrument transformers with rated voltages up to 132/\surd 3 kV using multitone test signals containing a HV fundamental component and superimposed harmonics up to 10 kHz. Such signals would represent the realistic operating conditions of HV instrument transformers. The performance of the developed system was analyzed by obtaining the voltage ratio and phase displacement of the reference capacitive voltage divider (CVD) from
