The paper focuses on the calibration techniques of non-conventional voltage and current measurement transformers. Calibration circuits set up at INRIM are described, which makes use of digital acquisition and numerical analysis of the transducer output. Examples of calibration of non-conventional instruments to be used as on-site references are discussed, which include a system based on Rogowski coil for live-on-site check of measuring current transformers with rated voltages up to 380 kV.
