The investigation involves the variation of power loss, building factor, the third harmonic distortion and flux leakages. The power loss and flux distribution have been measured using no load test in two types of model of setting of core built from the same size and type of M5 (CGO) grades material of laminations. And the loss of the transformer core without air gap of layer joint of core lamination is 2.75% better than the loss of the transformer core with air gap of layer joint of core lamination at 1.7T, 50 Hz. The flux leakage at the corner joint in the core without air gap of layer joint of lamination is lower than that in the transformer core with air gap of layer joint of lamination, over the whole flux density range. The third harmonic distortion of flux is smaller in the transformer core without air gap of layer joint of lamination and larger in the transformer core with air gap of layer joint of core lamination. Using the type without air gap of layer joint of lamination in transformer core is more efficient than the other types of transformer core lamination. 2008-09-19T02:03:48Z 2008-09-19T02:03:48Z 2007-12-06 Working Paper p.1-4 978-1-4244-1434-5 http://hdl.handle.net/123456789/2299 http://ieeexplore.ieee.org/xpls/abs_all.jsp?=&arnumber=4603874 en Proceedings of the Asia - Pacific Conference on Applied Electromagnetics (APACE 2007) Institute of Electrical and Electronics Engineering (IEEE) |
