외부부담이 전압변성기의 비오차와 위상각오차에 미치는 영향에 대한 연구 = A Study on Ratio Error and Phase Angle Error Caused by an External Burden in Voltage Transformer

다국어 초록 (Multilingual Abstract)

A voltage transformer(VT) used for the estabilishment of high voltage national standard, has generally ratio error and phase angle error. Both errors in VT depend critically on values of external burden of VT used. Both ratio error and phase angle error in existence of the external burden is calculated. These calculated values are very well consistent with the experimental result. The principle and the measurement method of VT in our institute are also explained.
