Resumo(s)
This paper presents the development and implementation
of a digital simulation model of a threephase,
three-leg, three-winding power transformer. The
proposed model, implemented in MATLAB environment,
is based on the simultaneous analysis of both magnetic
and electric lumped-parameters equivalents circuits, and it
is intended to study its adequacy to incorporate, at a later
stage, the influences of the occurrence of windings interturn
short-circuit faults. Both simulation and laboratory
tests results, obtained so far, for a three-phase, 6 kVA
transformer, demonstrate the adequacy of the model under
normal operating conditions.
