国家標準級インパルス校正器の不確かさ評価 Uncertainty Evaluation of National Standard Class Impulse Calibrator
Impulse voltage calibration is specified in IEC 61083-1 as a reference calibration method for the digital recorder used in the impulse voltage measuring system. Uncertainty of the calibrator needs to be specified to calibrate the digital recorder. The national standard class calibration system for the impulse voltage was developed in 2001 in Japan. At that time, the uncertainties of the wave shape parameters of its outputs were evaluated. The long term stability of the calibrator has been measured for five years, and the uncertainties of the system are re-evaluated this time.<br>In this letter, the estimation method of the uncertainty and re-evaluated uncertainties of the calibration system are described.
