Advanced industrial Loss Measurement Systems (LMS)

Commercial LMS are widely used by High Voltage (HV) transformer and reactor manufacturers. Typical state-of-the-art accuracies in industrial loss measurements are in the range of 1-3 % for power facto…

Primary reference setup for calibration of advanced industrial LMS

In the ELPOW project, a reference setup for reactor loss measurement was produced with a voltage range of 500 V, as well as reference setups for calibration of transformer LMS up to 100 kV but with an…

Uncertainty evaluation of loss measurements

An important extension of the state of the art is a study of detrimental factors that occur on-site in the industrial environment where these systems are used, such as interference and non-sinusoidal …
