Calibration of Voltage Transformer Test Sets using a Digital Sampling Wattmeter.

摘要

This paper describes the use of the NPL Digital Sampling Wattmeter (DSWM) [1] to calibrate voltage transformer test sets. These are instruments used to calibrate transformers by comparing the unknown transformer with a standard transformer whose properties are known. The standard transformer can be calibrated in a traceable fashion by a method such as that described in Ref [2].
