Языки: английский, французскийThis Standard applies to power transformers complying with the series of publications IEC 60076.
It is intended to provide information to users about:
– certain fundamental service characteristics of different transformer connections and magnetic circuit designs, with particular reference to zero-sequence phenomena;
– system fault currents in transformers with YNynd and similar connections;
– parallel operation of transformers, calculation of voltage drop or rise under load, and calculation of load loss for three-winding load combinations;
– selection of rated quantities and tapping quantities at the time of purchase, based on prospective loading cases;
– application of transformers of conventional design to convertor loading;
– measuring technique and accuracy in loss measurement.
