Measurement of harmonics in high-voltage networks has become increasingly important due to the increasing presence of harmonic voltages produced by power electronics in renewable energy generation plants. While new types of wideband voltage measurement devices are being deployed, the majority of voltage measurement instruments in the present high-voltage networks are still either the traditional inductive voltage transformers (IVTs) or the capacitive voltage transformers (CVTs). The traditional voltage transformers are designed for measuring at the power frequency and accuracy tests on these t...
