This Malaysian 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 convert or loading;–measuring technique and accuracy in loss measurement.
Malaysian Standard the information is of a general nature and applicable to all sizes of power transformers.Several chapters, however, deal with aspects and problems which are of the intere
