Deviation of short-circuit impedance from specified design value
Vitaly Gurin
Sažetak
The statistical processing of the measurement results of the short-circuit impedance of 1175 HV and EHV transformers, performed in 1983, is described. As feedback, recommendations were given to designers on the optimal choice of short-circuit impedance without the risk of unreasonable rejection of transformers during the testing phase. In the author's opinion, his recommendations have not lost
their significance up to this day.
