A new method determining the distribution of flux pinning energy U0, is described. The method is mainly the measurement of time dependent zero field critical current for sintered high temperature superconductor magnetized in applied field. By means of this method, the U0 distribution of Tl2Ba2Ca2Cu3Oy at 78K is obtained. Based on the experimental result, the dispersion of reported U0 is discussed.
