Calibration of voltage transformers and high-voltage …
This paper describes two different calibration services: high-voltage capacitors and voltage transformers. At NIST these two services are per- formed using the same equipment. In fact, in order to caUbrate a voltage transformer, one of the steps is to measure the ratio of two capacitors. The two services are therefore discussed in parallel.
