Calibration systems for analogue non-conventional voltage and current transducers

This paper describes the design and setup of different measuring systems for the calibration of both voltage and current transducers which are recently developed at VSL, PTB, and TUBITAK. The output levels of non-conventional transducers are adapted to traditional levels using step-up and step-down converters so that they can be measured using traditional measurement bridges. Verification and performance of a recently developed commercial transformer test set is investigated. The reference measuring systems are developed within the frame of the European project "FUTURE GRID - Non-conventional voltage and current sensors for future power grids".
