This two-part paper presents an inverse method to reconstruct the primary voltage of a VT from the available distorted secondary signals. In this second part, the performance of the proposed inverse method is validated by simulation using a 10 kV inductive voltage transformer (VT). Additionally, four laboratory experiments are performed to show the potential applications of the proposed method. These experiments closely represent realistic field conditions. The simulation and experimental results verify the accuracy and reliability of the method. The robustness and parameter accessibility are discussed. The novel inverse method provides an effective solution for the accurate reproduction of high-frequency transients and low-frequency over-voltages measurements. Furthermore, the reconstructed primary voltage waveforms provide usable data for the study of voltages in power systems.
