  1. 1. Analysis of factory test data of on-load tap-changers for power transformers

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Oscar Stenhammar; [2021]
    Keywords : on-load tap-changer; OLTC; power transformer;

    Abstract : On-load tap-changers (OLTC) are devices in the power grid that keeps the voltage level constant for consumers, regardless of the power demand. Hitachi ABB Power Grids, producer of the OLTC family named VUC, guarantees 30 years of lifetime. Such a pledge requires high standard devices. READ MORE
