Abstract

A harmonic error measurement system which can simulate the actual operating conditions of electronic instrument transformer was established for electronic instrument transformer harmonic error measurement. The system consists of High-power current and voltage harmonic source which is used to output fundamental and harmonic signal, harmonic voltage and current standard device and harmonic analyzer. The results indicate that after superposing the fundamental and harmonic, ratio and phase error of electronic current transformer (ECT) becomes larger with increasing frequency; ratio error of electronic voltage transformer(EVT) increases with the increasing harmonics frequency, but EVT phase error changed to negative value at rated current, 150Hz frequency.
