Calibration of voltage transformers and high-voltage capacitors at NIST

Journal of Research of the National Bureau of Standards, 1989
The National Institute of Standards and Technology (NIST) calibration service for voltage transformers and high-voltage capacitors is described. The service for voltage transformers provides measurements of ratio correction factors and phase angles at primary voltages up to 170 kV and secondary voltages as low as 10 V at 60 Hz.
