Penentuan Pembebanan Maksimum Transformator Daya Yang Menyuplai Personal Computer (PC)
Abstract: Personal computer is
electronic equiment that use solid state device, such as rectifiers, so it to
be source of harmonic current. Harmonic current is sinusoidal current with
multiple frequency of fundamental current which will be increase power losses
because increasing effective current and frequency. In electric distribution
system, transformer is component with highest power losses. They are consit of
DC losses (Pdc) that influence by effective current, eddy current (PEC) and other
stray losses (POSL) which influence by effective current and their frequency.
This study involved increasing transformer power losses with assume that
transformer supply in full load condition to personal computer. Analyzes
following IEEE Std. C57.110-1998 with comparing determination maximum
transformer loading use current spectrum from spectrum analyzer equipment and
conversion produce Mathlab from current wave time domain to current wave
frequency domain. The result are maximum transformer loading is 97,84 use
spectrum analyzer and 97,84 use Mathlab sofware.
