摘要：
In the present paper the calibration of AC high voltage using the precision grade standard voltage transformer (used as a voltage divider) and standard digital voltmeter taking a case study of Electrostatic Voltmeter are discussed. Various sources of the uncertainty in measurement and their estimation based on Type A and Type B method as per ISO/IEC 17025 guidelines are also discussed. The results are reported at k = 2 for approx. 95 per cent confidence level. The standards used for calibration are traceable to the 'National Standards'.
